7. Functional description

7.1 Low-noise RF amplifier

The Low Noise Amplifier (LNA) input impedance together with the LC RF input circuit
defines an FM band filter. The gain of the LNA is controlled by the RF AGC circuit.

7.2 FM mixer

The FM quadrature mixer converts the FM RF (76 MHz to 108 MHz) to an IF of 225 kHz.

7.3 VCO

The varactor tuned LC VCO provides the Local Oscillator (LO) signal for the FM
quadrature mixer. The VCO frequency range is 150 MHz to 217 MHz.

Product data sheet Rev. 05 — 26 January 2007 6 of 40

NXP Semiconductors

7.4 Crystal oscillator

The crystal oscillator can operate with a 32.768 kHz clock crystal or a 13 MHz crystal. The
temperature drift of standard 32.768 kHz clock crystals limits the operational temperature
range from −10 °Cto+60°C.

The PLL synthesizer can be clocked externally with a 32.768 kHz, a 6.5 MHz or a 13 MHz
signal via pin XTAL2.

The crystal oscillator generates the reference frequency for:

• The reference frequency divider for the synthesizer PLL

• The timing for the IF counter

• The free-running frequency adjustment of the stereo decoder VCO

• The center frequency adjustment of the IF filters

7.5 PLL tuning system

The PLL synthesizer tuning system is suitable to operate with a 32.768 kHz or a 13 MHz
reference frequency generated by the crystal oscillator or applied to the IC from an
external source. The synthesizer can also be clocked via pin XTAL2 at 6.5 MHz. The PLL
tuning system can perform an autonomous search tuning function.

TEA5767HN

Low-power FM stereo radio for handheld applications

7.6 RF AGC

The RF AGC prevents overloading and limits the amount of intermodulation products
created by strong adjacent channels.

7.7 IF filter

Fully integrated IF filter.

7.8 FM demodulator

The FM quadrature demodulator has an integrated resonator to perform the phase shift of
the IF signal.

7.9 Level voltage generator and analog-to-digital converter

The FM IF analog level voltage is converted to 4 bits digital data and output via the bus.

7.10 IF counter

The IF counter outputs a 7-bit count result via the bus.

7.11 Soft mute

The low-pass filtered level voltage drives the soft mute attenuator at low RF input levels.
The soft mute function can be switched off via the bus.

7.12 MPX decoder

The PLL stereo decoder is adjustment-free. The stereo decoder can be switched to mono
via the bus.

NXP Semiconductors

7.13 Signal dependent mono to stereo blend

With a decreasing RF input levelthe MPX decoder blends from stereo to mono to limit the
output noise. The continuous mono to stereo blend can also be programmed via the bus
to an RF level depending switched mono to stereo transition. Stereo Noise Cancelling
(SNC) can be switched off via the bus.

7.14 Signal dependent AF response

The audio bandwidth will be reduced with a decreasing RF input level. This function can
be switched off via the bus.

7.15 Software programmable ports

Two software programmable ports (open-collector) can be addressed via the bus.
The port 1 (pin SWPORT1) function can be changed with write data byte 4 bit 0

(see Table 13). Pin SWPORT1 is then output for the ready flag of read byte1.

7.16 I2C-bus and 3-wire bus

TEA5767HN

Low-power FM stereo radio for handheld applications

The 3-wire bus and the I2C-bus operate with a maximum clock frequency of 400 kHz.
Before any READ or WRITE operation the pin BUSENABLE has to be HIGH for at

least 10 µs.
The I2C-bus mode is selected when pin BUSMODE is LOW, when pin BUSMODE is HIGH

the 3-wire bus mode is selected.

Information about the I2C-bus can be found in the brochure

it” (order number 9398 393 40011)

The standard I2C-bus specification is expanded by the following definitions:

IC address: 110 0000b
Structure of the I2C-bus logic: slave transceiver
Subaddresses are not used
The maximum LOW-level input and the minimum HIGH-level input are specified to

0.2V
The pin BUSMODE must be connected to ground to operate the IC with the I2C-bus.

Remark: The I2C-bus operates at a maximum clock frequency of 400 kHz. It is not
allowed to connect the IC to an I2C-bus operating at a higher clock rate.

and 0.45V

CCD

8.1.1 Data transfer

Data sequence: address, byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to
be in this order). The Least Significant Bit (LSB) = 0 of the address indicates a WRITE
operation to the TEA5767HN.

Bit 7 of each byte is considered as the Most Significant Bit (MSB) and has to be
transferred as the first bit of the byte.

The data becomes valid bitwise at the appropriate falling edge of the clock. A STOP
condition after any byte can shorten transmission times.

respectively.

CCD

“The I2C-bus and how to use

.

When writing to the transceiver by using the STOP condition before completion of the
whole transfer:

• The remaining bytes will contain the old information

• If the transfer of a byte is not completed, the new bits will be used, but a new tuning

cycle will not be started

The IC can be switched into a low current Standby mode with the standby bit; the bus is
then still active. The standby current can be reduced by deactivating the bus interface
(pin BUSENABLE LOW). If the bus interface is deactivated (pin BUSENABLE LOW)
without the Standby mode being programmed, the IC maintains normal operation, but is
isolated from the bus lines.

The software programmable output (SWPORT1) can be programmed to operate as a
tuning indicator output. As long as the IC has not completed a tuning action,
pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is
completed or when a band limit is reached.

The reference frequency divider of the synthesizer PLL is changed when the MSB in
byte 5 is set to logic 1. The tuning system can then be clocked via pin XTAL2 at 6.5 MHz.

8.3 3-wire bus specification

The 3-wire bus controls the write/read, clock and data lines and operates at a maximum
clock frequency of 400 kHz.

Hint: By using the standby bit the IC can be switched into a low current Standby mode. In
Standby mode the IC must be in the WRITE mode. When the IC is switched to READ
mode, during standby, the IC will hold the data line down. The standby current can be
reduced by deactivating the bus interface (pin BUSENABLE LOW). If the bus interface is
deactivated (pin BUSENABLE LOW) without the Standby mode being programmed, the
IC maintains normal operation, but is isolated from the clock and data line.

8.3.1 Data transfer

Data sequence: byte 1, byte 2, byte 3, byte 4 and byte 5 (the data transfer has to be in this
order).

TEA5767HN_5 © NXP B.V. 2007. All rights reserved.

Product data sheet Rev. 05 — 26 January 2007 12 of 40

NXP Semiconductors

A positive edge at pin WRITE/READ enables the data transfer into the IC. The data has to
be stable at the positive edge of the clock. Data maychange while the clock is LOW and is
written into the IC on the positive edge of the clock. Data transfer can be stopped after the
transmission of new tuning information with the first two bytes or after each following byte.

A negative edge at pin WRITE/READ enables the data transfer from the IC. The
WRITE/READ pin changes while the clock is LOW. With the negative edge at
pin WRITE/READ the MSB of the first byte occurs at pin DATA.

The bits are shifted on the negative clock edge to pin DATA and can be read on the
positive edge.

To do two consecutive read or write actions, pin WRITE/READ has to be toggled for at
least one clock period. When a search tuning request is sent, the IC autonomously starts
searching the FM band; the search direction and search stop level can be selected. When
a station with a field strength equal to or greater than the stop level is found, the tuning
system stops and the ready flag bit is set to HIGH. When, during search, a band limit is
reached, the tuning system stops at the band limit and the band limit flag bit is set to
HIGH. The ready flag is also set to HIGH in this case.

TEA5767HN

Low-power FM stereo radio for handheld applications

The software programmable output (SWPORT1) can be programmed to operate as a
tuning indicator output. As long as the IC has not completed a tuning action,
pin SWPORT1 remains LOW. The pin becomes HIGH, when a preset or search tuning is
completed or when a band limit is reached.

The reference frequency divider of the synthesizer PLL is changed when the MSB in
byte 5 is set to logic 1. The tuning system can then be clocked via pin XTAL2 at 6.5 MHz.

8.3.2 Power-on reset

At Power-on reset the mute is set, all other bits are random. To initialize the IC all bytes
have to be transferred.

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

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:

TEA5767HN

Low-power FM stereo radio for handheld applications

AN10365 “Surface mount reflow

.

• 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

• Solder paste printing issues including smearing, release, and adjusting the process

• Reflow temperature profile; this profile includes preheat, reflow (in which the board is

Table 35. SnPb eutectic process (from J-STD-020C)

Package thickness (mm) Package reflow temperature (°C)

< 2.5 235 220

TEA5767HN

Low-power FM stereo radio for handheld applications

higher minimum peak temperatures (see Figure 15) than a PbSn process, thus
reducing the process window

window for a mix of large and small components on one board

heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough forthe 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 35 and 36

Volume (mm3)
< 350 ≥ 350

Table 36. Lead-free process (from J-STD-020C)

Package thickness (mm) Package reflow temperature (°C)

< 1.6 260 260 260

1.6 to 2.5 260 250 245
> 2.5 250 245 245

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 15.
