7. Functional description
7.1 FM mixer 1
The FM quadrature mixer converts FM RF (65 MHz to 108 MHz) to an IF frequency of
10.7 MHz. The FM mixer provides high image rejection, a large dynamic range and
selectable mixer gain. The image rejection can be selected between low injection of LO
and high injection of LO via the I2C-bus independently of the band selection. A separate
RF input for weather band is available.
7.2 FM RF AGC
AGC detection is at the FM front-end mixer input and the AM/FM IF AGC amplifier input,
both with programmable AGC thresholds. When the threshold is exceeded, the PIN diode
drive circuit sources a current to an external PIN diode circuit, keeping the RF signal level
constant.
Keyed AGC function is selectable via the I2C-bus and uses the in-band level information
from the IF DSP.
The AGC PIN diode drive circuit can optionally deliver a fixed current as a local function.
In AM mode, the AGC PIN diode drive circuit can be set to generate a fixed source current
into the external FM PIN diode circuitry.
7.3 Antenna DAA1 and DAA2
The antenna DAA1 measures the VCO tuning voltage and multiplies it with a factor
defined by the 7-bit DAA1 setting to generate a tuning voltage for the FM antenna tank
circuit. If a second FM tank circuit is applied, the tuning voltage can be derived from the
antenna DAA2 output. The antenna DAA2 measures the output voltage of the antenna
DAA1 and multiplies it with a factor defined by the 4-bit DAA2 setting.

7.4 AM LNA
The AM low noise amplifier is fully integrated.
7.5 AM RF AGC
The AM RF AGC is partially integrated. Detection is at the output of the AM LNA and at
the input of the AM/FM IF AGC amplifier, both with programmable thresholds. First the
integrated AGC reduces the gain of the LNA. After the LNA AGC, the PIN diode AGC
takes over by sinking a current via an external PIN diode.
In FM mode, the AM AGC can be set to a fixed attenuation.
7.6 AM mixer
The large dynamic range AM mixer converts AM RF (144 kHz to 26.1 MHz) to an IF
frequency of 10.7 MHz.
7.7 VCO and dividers
The varactor tuned LC oscillator together with the dividers provides the LO signal for both
AM and FM front-end mixers. The VCO has an operating frequency of approximately
160 MHz to 256 MHz. In FM mode the LO frequency is divided by 2 or 3. These dividers
generate in-phase and quadrature-phase output signals used in the FM front-end mixer
for image rejection. In weather band mode the LO signal is directly phase shifted to
generate the in-phase and quadrature-phase signals. In AM mode the LO frequency is
divided by 6, 8, 10, 16 or 20 depending on the selected AM band.
7.8 Tuning PLL
The tuning PLL locks the VCO frequency divided by the programmable divider ratio to the
reference frequency. Due to the combination of different charge pump signals in the
PLL loop filter, the loop parameters are adapted dynamically. Tuning to different
RF frequencies is done by changing the programmable divider ratio. The tuning step size
is selected with the reference frequency divider setting.
7.9 AM/FM IF AGC amplifier
The combined AM/FM IF AGC amplifier delivers a suitable IF signal for the ADC in the
IF DSP. The maximum gain of the IF AGC amplifier can be selected via the I2C-bus. The
gain of this amplifier is automatically adapted via interfacing signals from the IF DSP. The
IF AGC amplifier has three signal inputs, two for FM and one for AM. This allows the
application of multiple external filters, e.g. with different bandwidths.

The tuner circuit is controlled by the CONTROL register. Any data change in the
CONTROL register has immediate effect and will change the operation of the tuner circuit
accordingly. Transmitted I2C-bus data is not loaded into the CONTROL register directly
but loaded into a BUFFER register instead. This allows the IC to take care of tuning
actions freeing the microcontroller from cumbersome controls and timings.
Controlled by a state machine, the BUFFER data will be loaded into the CONTROL
register for new settings. However, at the same time the CONTROL data is loaded into the
BUFFER register. This register swap action allows a fast return to the previous setting
because the previous data remains available in the BUFFER register (see Figure 6 and
Figure 7).
Via MODE several operational modes can be selected for the state machine. MODE offers
all standard tuning actions as well as generic control for flexibility. The state machine
controls the tuner by controlling the internal I2C-bus data. Action progress is monitored by
the accompanying IF DSP via the AFSAMPLE and AFHOLD lines. This way, functions like
tuning mute and weak signal processing can be controlled complementary to the tuner
action.
The state machine operation starts at the end of transmission (P = STOP). In case a
previous action is still active, this is ignored and the new action defined by MODE is
started immediately. When only the address byte is transmitted, no action is started at all
(device presence test).
To minimize the I2C-bus transmission time, only bytes that include data changes need to
be written. Following the MSA byte the transmission can start at any given data byte
defined by the subaddress (SA) bits.
Furthermore, when writing the buffered range either the current BUFFER data or the
current CONTROL data can be used as default, controlled by the REGC bit:
With REGC = 0, any BUFFER data that is not newly written via I2C-bus remains
unchanged. In general, the BUFFER register will contain the previous tuner setting, so
this becomes default for the new setting. When only the MSA byte is transmitted
defining a tuning MODE with REGC = 0, the tuner will return to its previous settings
(see Figure 6).
With REGC = 1, the BUFFER register is loaded with data from the CONTROL register
first. This way, not written BUFFER data equals the CONTROL data. Since the
CONTROL register contains the current tuner setting with REGC = 1, the current
tuner setting is default for the new setting. When a tuning MODE action is defined with
REGC = 1, the tuner will keep its current settings (CONTROL = current) for all data
that is not newly written during the transmission (see Figure 7).
After power-on reset, all registers are in their default settings. The control signals for the
IF DSP are set to AFSAMPLE = HIGH and AFHOLD = HIGH (i.e. mute state). Any action
of the state machine will change this setting to a new one as defined by the bits
MODE[2:0].

8.2.1 Mode and subaddress byte for write
[1] When the write transmission of a state machine command starts during a mute state of the state machine,
the sequences of the state machine start immediately with the actions which follow the mute period in the
standard sequence (see Figure 9,Figure 11,Figure 13,Figure 15 and Figure 17).
[2] References to mute are only used for better understanding. Muting is performed in the IF DSP controlled by
the tuner AFHOLD and AFSAMPLE lines.
[3] In the modes preset and search the AM AGC time constant is set to fast during the period of complete
mute.
[4] The AF update sequence can also be started by pulling the AFHOLD pin LOW. In this case the AF
information should be loaded into the BUFFER before. LOW period for a correct AF update timing:
tLOW >20µs. Between the end of the I2C-bus transmission and the falling edge of the AFHOLD pulse a
delay of 20 µs is necessary.

13. I2C-bus characteristics
The TEF6730AHW complies with the fast-mode I2C-bus protocol. The maximum I2C-bus
communication speed is 400 kbit/s.
SDA and SCL HIGH and LOW internal thresholds are specified according to an I2C-bus
voltage range from 2.5 V to 3.3 V including I2C-bus voltage tolerances of ±10 %. The
I2C-bus interface tolerates also SDA and SCL signals from a 5 V bus. Restrictions for VIL
in a 5 V application can be derived from Table 37.

18. Soldering
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note
AN10365 “Surface mount reflow
soldering description”
.
18.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
18.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
Through-hole components
Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus PbSn soldering
18.3 Wave soldering
Key characteristics in wave soldering are:
Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
Solder bath specifications, including temperature and impurities

18.4 Reflow soldering
Key characteristics in reflow soldering are:
Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 32) than a PbSn process, thus
reducing the process window
Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 41 and 42
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 32.
