FUNCTIONAL DESCRIPTION
Low-noise RF amplifier
The PLL synthesizer can be clocked externally with a
32.768 kHz, a 6.5 MHz or a 13 MHz signal via pin XTAL2.
7.1
The crystal oscillator generates the reference frequency
for:
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.
• The reference frequency divider for the synthesizer PLL
• The timing for the IF counter
7.2
FM mixer
• The free-running frequency adjustment of the stereo
decoder VCO
The FM quadrature mixer converts the FM RF
(76 MHz to 108 MHz) to an IF of 225 kHz.
• The centre frequency adjustment of the IF filters.
7.3
VCO
7.5
PLL tuning system
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.
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.
7.4
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.
7.6
RF AGC
The RF AGC prevents overloading and limits the amount
of intermodulation products created by strong adjacent
channels.

I2C-BUS AND BUS-CONTROLLED FUNCTIONS
I2C-bus specification

IF filter
8
Fully integrated IF filter.
8.1
Information about the I2C-bus can be found in the brochure
“The I2C-bus and how to use it” (order number
9398 393 40011).
7.8
FM demodulator
The FM quadrature demodulator has an integrated
resonator to perform the phase shift of the IF signal.
The standard I2C-bus specification is expanded by the
following definitions.
7.9
Level voltage generator and analog-to-digital
converter
IC address C0: 1100000.
Structure of the I2C-bus logic: slave transceiver.
Subaddresses are not used.
The FM IF analog level voltage is converted to 4 bits digital
data and output via the I2C-bus.
7.10 IF counter
The maximum LOW-level input and the minimum
HIGH-level input are specified to 0.2VCCD and 0.45VCCD
respectively.
The IF counter outputs a 7-bit count result via the I2C-bus.
7.11 Soft mute
The pin BUSMODE must be connected to ground.
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.
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.
7.12 MPX decoder
The PLL stereo decoder is adjustment-free. The stereo
decoder can be switched to mono via the I2C-bus.
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
LSB = 0 of the address indicates a WRITE operation to the
TEA5768HL.
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
continuous mono to stereo blend can also be programmed
via the I2C-bus to an RF level depending switched mono to
stereo transition. Stereo Noise Cancelling (SNC) can be
switched off via the I2C-bus.
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.
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
I2C-bus.
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.
7.15 Software programmable ports
Two software programmable ports (open-collector) can be
addressed via the I2C-bus.
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 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.
2004 Sep 13
8
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.
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.
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.

Notes
1. Calculation of this 14-bit word can be done as follows:
4 × (fRF + fIF)
4 × (fRF – fIF)
formula for HIGH side injection: N =
; formula for LOW side injection: N =
----------------------------------
---------------------------------
fref
fref
where:
N = decimal value of PLL word
fRF = the wanted tuning frequency [Hz]
fIF = the intermediate frequency [Hz] = 225 kHz
fref = the reference frequency [Hz] = 32.768 kHz for the 32.768 kHz crystal; fref = 50 kHz for the 13 MHz crystal or
when externally clocked with 6.5 MHz.
4 × (100×106 + 225×103)
Example for receiving a channel at 100 MHz with HIGH side injection: N =
= 12234 .
------------------------------------------------------------------
32768
The PLL word becomes 2FCAH.
2. VRF in Fig.5 is replaced by VRF1 + VRF2. The radio is tuned to 98 MHz (HIGH side injection).
3. LOW side and HIGH side selectivity can be switched by changing the mixer from HIGH side to LOW side LO injection.

16 SOLDERING
To overcome these problems the double-wave soldering
method was specifically developed.
16.1 Introduction to soldering surface mount
packages
If wave soldering is used the following conditions must be
observed for optimal results:
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
16.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Driven by legislation and environmental forces the
The footprint must incorporate solder thieves at the
downstream end.
• For packages with leads on four sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
worldwide use of lead-free solder pastes is increasing.
Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 seconds and 200 seconds
depending on heating method.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical reflow peak temperatures range from
215 °C to 270 °C depending on solder paste material. The
top-surface temperature of the packages should
preferably be kept:
Typical dwell time of the leads in the wave ranges from
3 seconds to 4 seconds at 250 °C or 265 °C, depending
on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
• below 225 °C (SnPb process) or below 245 °C (Pb-free
process)
– for all BGA, HTSSON..T and SSOP..T packages
16.4 Manual soldering
– for packages with a thickness ≥ 2.5 mm
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
– for packages with a thickness < 2.5 mm and a
volume ≥ 350 mm3 so called thick/large packages.
• below 240 °C (SnPb process) or below 260 °C (Pb-free
process) for packages with a thickness < 2.5 mm and a
volume < 350 mm3 so called small/thin packages.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 seconds to 5 seconds
between 270 °C and 320 °C.
Moisture sensitivity precautions, as indicated on packing,
must be respected at all times.
16.3 Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy
from your Philips Semiconductors sales office.
2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
5. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
6. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than
0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
9. Hot bar soldering or manual soldering is suitable for PMFP packages.
