7 FUNCTIONAL DESCRIPTION
7.1 Low-noise RF amplifier
The 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.
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 °C to +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 centre 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.
7.6 RF AGC
The RF AGC prevents overloading and limits the amount
of intermodulation products created by strong adjacent
channels.

Philips Semiconductors Product specification
Low-power FM stereo radio for
handheld applications TEA5768HL
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
TheFMIFanaloglevelvoltage is convertedto4 bits digital
data and output via the I2C-bus.
7.10 IF counter
The IF counter outputs a 7-bit count result via the I2C-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 I2C-bus.
7.12 MPX decoder
The PLL stereo decoder is adjustment-free. The stereo
decoder can be switched to mono via the I2C-bus.
7.13 Signal dependent mono to stereo blend
With a decreasing RF input level the MPX decoder blends
from stereo to mono to limit the output noise. The
continuousmonotostereoblend can also be programmed
viathe I2C-bus to an RFleveldepending switched mono to
stereo transition. Stereo Noise Cancelling (SNC) can be
switched off via the I2C-bus.
7.14 Signal dependent AF response
Theaudio bandwidth will be reduced with a decreasing RF
input level. This function can be switched off via the
I2C-bus.
7.15 Software programmable ports
Two software programmable ports (open-collector) can be
addressed via the I2C-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 byte 1.
8I
2C-BUS AND BUS-CONTROLLED FUNCTIONS
8.1 I2C-bus specification
InformationabouttheI2C-buscanbefoundinthe brochure
“The I
2
C-bus and how to use it” (order number
9398 393 40011).
The standard I2C-bus specification is expanded by the
following definitions.
IC address C0: 1100000.
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 0.2VCCD and 0.45VCCD
respectively.
The pin BUSMODE must be connected to ground.
Before any READ or WRITE operation the pin
BUSENABLE has to be HIGH for at least 10 µs.
Note: The bus operates at a maximum clock frequency of
400 kHz. It is not allowed to connect the IC to a bus
operating at a higher clock rate.
8.1.1 DATA TRANSFER
Datasequence:address, byte 1,byte 2, byte 3,byte 4and
byte 5 (the data transfer has to be in this order). The
LSB = 0of the addressindicatesa WRITE operation tothe
TEA5768HL.
Bit 7 of each byte is considered as the 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.
When writing to the transceiver by using the STOP
condition before completion of the whole transfer:
•The remaining bytes will contain the old information
•Ifthetransferofa 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.

2004 Sep 13 9
Philips Semiconductors Product specification
Low-power FM stereo radio for
handheld applications TEA5768HL
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.
8.1.2 POWER-ON RESET
At Power-on reset the mute is set, all other bits are set to
LOW. To initialize the IC all bytes have to be transferred.
