Functional Description
The evaluation board accommodates the synthesizer by
providing clock circuitry, a PC interface, and other
support circuitry necessary for operation.
Synthesizer
The heart of the evaluation board is the Silicon
Laboratories frequency synthesizer. This section
includes the synthesizer integrated circ uit (IC), external
tuning components, output matching, and power supply
decoupling circuitry.
For devices requiring an external inductor to establish
the center frequ ency fo r the RF 1 and RF2 synthe sizers ,
the inductor is implemented with a printed trace. The IF
synthesizer inductor is set by an 0402-size chip
inductor. The inductors are set for the nominal center
frequencies shown in Table 1.
Outputs of the synthesizers are ac-coupled and
matched to a 50 load impedance. SMA connectors
are provided for easy connection to measurement
equipment or to target systems. Output JRF1 is
multiplexed between the RF1 and RF2 syn thesizers and
is toggled through the evaluation software. See the
synthesizer data sheet for more detail. The second
output, JIF1, is connected to the IF synthesizer output.
Both the multiplexed RF output and the IF output can be
active simultaneously. Synthesizers are independently
enabled using the radio buttons in the evaluation
software.
The synthesizer IC is supplied by three different power
supplies. VDDR supplies the analog circuitry for the
RF1 and RF2 synthesizers. VDDI supplies the analog
circuitry for the IF synthesizer, and VDDD supplies the
digital prescaler, serial interface, and reference input
circuitry. Each of these supplies is bypassed to ground
with a 22 nF capacitor close to the body of the IC.
PC Interface
The frequency synthesizer IC uses a serial interface for
programming. The three primary signals are serial data
(SDATA), serial clock (SCLK), and serial enable
(SENB). These are all mapped to data pins of the PC’s
parallel port. Data is read back from the IC using the
BUSY input of the parallel port and SCLK.
One additional signal, GPO, is a multipurpose signal
used to cont rol the synthesizer’s hardware power -down
enable (PWDNB) and/or to trigger external test
equipment. The intended use is for power-up and
channel-to-channel settling time measurements. See
the "Evaluation Software" section for more detail.
Clock Circuitry
The reference frequency for the synthesizer is
generated on-board by a temperature-compensated,
voltage-tuned, crystal oscillator. The circuit is flexible to
allow evaluation with an external reference source or
with diffe ren t freq ue ncy oscil lators in varying packa ges.
Header JP6 selects the reference frequency source to
the frequency synthesizer IC. Either the on-board
oscillator or the external SMA input, J8, can be
selected.
The tuning control of the oscillator, Vc, is fixed at
(Vsupply/2) by R19 and R20. C14 provides filtering for
noise reduction on the tuning input. Test points JP9 and
JP10 allow easy connection to the tuning voltage for
external frequency trimming or reference modulation.
Power Supplies
The evaluation board requires a 5 V supply at JP11 to
power the digital interface to the PC. The synthesizer’s
supply voltage can be taken from the on-board 3 V
regulator or a user-supplied voltage at JP11 depending
on the jumper setting at JP4.

AUXOUT
The AUXOUT pin of the frequency synthesizer can be
programmed for a variety of functions. The evaluation
board is normally populated so that this pin can be read
by the PC for serial reads from the IC. Other functions
can be monitored on the AU XOUT test point as well.
Refer to the appropriate synthesizer data sheet for
details of AUXOUT’s functionality and configuration.
Hardware Power Down
The hardware power-down input, PWDNB, can be
driven several different ways on the evaluation board.
The default configuration is pulled high (enabled)
through a resistive pull-up, R21. This pin may be
controlled through an external source or via evaluation
software.
To control PWDNB with an external generator, place a
shorting block on JP3. There should not be a shorting
block on JP2. Connect the output of the generator to
test point PWDNB. The test point labeled GND should
be connected to the shield of the cable.
The evaluation software can power down the
synthesizer through the PWDNB pin. JP2 and JP3 must
both be jumpered to use this feature. The PWDNB test
point can then be used to monitor the PWDNB signal.
Refer to the appropriate synthesizer data sheet for a
complete explanation of software and hardware power
management options.

Evaluation Software
The Silicon Laboratories evaluation software is a
graphical, Windows-based user interface to the Silicon
Laboratories synthesizer family. The interface allows the
user to directly enter counter integers, frequencies, or
control bits without the need to compute and format bit-
level register information. Hardware connection to the
evaluation board is through a sta ndard parallel port.
Installation
After the CD is inserted into the computer, the installer
should run automatically. The installer can also be
invoked by running the “Installer.exe” program at the
root directory of the CD. The CD contains installers for
several programs. Select the appropriate device from
the list.
Window Overview
Control data may be e ntered in a variety of ways. Each
numerical parameter can either be entered directly from
the keyboard by selecting the box and typing or can be
stepped using the up/down arrow keys. Control bits are
selected or deselected by radio butto ns.
Note: The windows shown in these figures are specific to the
Si4133 Programmer, version 1.3.6. Evaluation soft-
ware and options may vary for other synthesizers and
software versions.
Figure 1. Evaluation Software
Si4133/33G-EVB

Controls
The various controls are described below.
Reference Divider, Reference Frequency, and
Update Rate
The reference divider value sets the update rate of the
phase detector for a given reference frequency. This
value can be set by either using the R-Divider input, the
Reference input, or the Update Rate input. All of these
controls are linked to set the R Divider in the
synthesizer. Writing to any of these registers for RF1 or
RF2 will select the associated synthesizer at the
RFOUT output.
The R-Divider input directly sets the R Divider of the
synthesizer. Changes made to this value will then
change the update ra te and the synthesized frequency.
The Reference input changes all R Dividers to values
such that the update rate and synthesized frequency
remain at approximately the same value for the entered
reference frequency. Note that this changes only the
R Divider not the actual reference frequency of the on-
board oscillator.
Changing the Update Rate input changes the R and
N Dividers to maintain the same synthesized frequency
for a given reference frequency.
Phase Detector
The phase detector value window sets the relative gain
of the phase detector. Refer to the appropriate
synthesizer data sheet for further information about
setting of the phase detector gain.
The Auto KP option will automatically select the best KP
for phase noise, settling time, and loop stability.
VCO and N Divider
The N Divider can be set by an integer in the N-Divider
register or by a decimal frequency in the VCO window.
Writing to either of these registers for RF1 or RF2 will
select the associated synthesizer at the JRF1
connector. The N-Divider window writes directly to the
N Divider of the synthesizer.
The values entered in the VCO register will cause the
software to automatically compute and set the N
register to generate the specified frequency.
RF Select
The RF Select toggle switch selects the RF1 or RF2
synthesizer output on the JRF1 connector. This control
does not correspond to an actual control bit.
Synthesizers are toggled by writing to the N Divider of
the selected synthesizer. User applications should
select the active synthesizer by writing to the N or R
register as outlined in the appropriate synthesizer data
sheet.
Auxiliary Output Control
Auxiliary Output Control selects the function of the
AUXOUT pin. This pin can be used to monitor various
functions internal to the synthesizer. Refer to the
appropriate synthesizer data sheet for details.
This pin also performs the serial read function of the
synthesizer registers by the PC. Serial data will appear
at this pin if “Verify Device Writes” or if the VCO Tuning
Meters are enabled in the SiLabs pull-down menu.
Power Down Control
The Power Down Control radio buttons select the
various software power-down options of the frequency
synthesizer IC. (See Figure 2.) The label for each radio
button corresponds to the name of the control bit being
programmed. See the appropriate synthesizer data
sheet for a complete description of power control
options.
Figure 2. Power-Down Control Radio Buttons
AUTOPDB, Force All On, forces the reference amplifier,
the RF synthesizers, and the IF synthesizer on. These
synthesizers can be enabled independently of each
other using PDIB and PDRB.
The hardware PWDNB input overrides all power-up
settings selected in this window. The serial interface
remains active when powered down.
Menus and Options
Menus and options are descr ibed below.
File Menu
The File menu allows register configurations to be
saved and restored. By default, configurations are
stored as .cfg files in the Configurations folder within the
Si4133 Programmer folder. (See Figure 3.)

Figure 3. File Menu
The configuration files are text files and can be viewed
and edited with a text editor such as Microsoft
Notepad™ or Wordpad™.
Edit Menu
The Edit menu allows for copy and paste operations
between input windows. (See Figure 4.)
Figure 4. Edit Menu
SiLabs Menu
The SiLabs menu contains the controls specific to the
Silicon Laboratories evaluation software and its
hardware interface. (See Figure 5.)
Figure 5. SiLabs Menu
Selecting Write All Registers refreshes all registers of
the frequency synthesizer IC. This should be selected
upon power up to ensure all r egisters are refreshed.
Selecting Verify Device Writes reads and verifies the
content of the registers as they are written. If a
discrepancy occurs, a pop-up window will show “Device
Write Verification Failed.” (See Figure 6.)
Figure 6. Write Fail
The data is read from the frequency synthesizer to the
PC through the AUXOUT port. Data read from this
register temporarily overrides the function programmed
to this pin.
Show VCO Tuning enables graphical, meter-type
displays of the self-tuning results of each VCO. The
VCO tuning meters are useful when selecting the
values for external inductances or monitoring lock
behavior. When the needle is at the extreme left of the
display, the VCO is operating at the lower end of its
frequency range. Similarly, when the needle is at the
extreme right of the display, the VCO is operating at the
upper end of it s frequency range. (See Figure 7.)

Figure 7. VCO Tuning
Detailed information on the op eration and interpretation
of the self-tuning algorithm is available in the appendix
of the frequency synthesizer data sheet entitled,
“Evaluating Self Tuning Results.”
The Show Register Values option enables a display of
the contents of the synthesizer registers. (See
Figure 8.) This is useful in computing register values for
application software or for debugging. Refer to the
Control Register section of the applicable synthesizer
data sheet for definition of the values shown.
Figure 8. Show Registers
The Loop Utility allows the user to automatically toggle
between two register settings as shown in Figure 9.
Applications include power-up settling time and
channel-to-channel settling time measurements. The
GPO hardware port is also controlled through the Utility
switch in this window to either power down the
synthesizer through its hardware port or to trigger
external test equipment to correspond to a register
write.
Figure 9. Loop Utility
Si4133/33G-EVB
Rev. 0.6 9
The loop executes sequentially when the green Loop
button is selected and repeats until the red Stop button
is pressed. There are four steps. In the first, the register
selected in the First Register pull-down box is written
with the value in the First Value box. The GPO
hardware signal on the evaluation board is set high or
low dependent on the First Utility switch setting.
The second step is a delay, entered in milliseconds. The
third and fourth steps are set similarly to the first and
second.
The configuration shown in Figure 9 could be used to
measure channel-to-channel settling time. Steps 1 and
2 set the N counter of the RF1 synthesizer to a given
frequency, set the GPO utility signal low, and then
pause for 100 milliseconds. Steps 3 and 4 then
reprogram the N counter for a different frequency, set
the GPO utility port high to trigger measurement
equipment, and delay for another 100 ms. The loop
repeats so that the measurement equipment can
average over several channel changes. In this
measurement, the evaluation board should have J2 and
JP3 jumpered so that the GPO signal is routed to the
PWDNB test point for connection to the test equipment
trigger port and also to the PWDNB pin of the
synthesizer.
The Open Loop... menu selection invokes the window
shown in Figure 10. By setting the VCO to operate at its
minimum and maximum frequencies, the center
frequency can be calculated by averaging these two
extremes.
Figure 10. Open Loop Menu
Selecting Device ID... causes a pop-up window to
appear with an internal de vice code displayed.
Selecting Set Parallel Port allows the user to select
either LPT1 or LPT2 to control the evaluation boar d.
