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

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

Product data sheet Rev. 01 — 21 February 2007 53 of 58

NXP Semiconductors TEF6730A

Front-end for digital-IF car radio

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.
