By changing the value of the input resistor at pin 12 the
MPX input can be adapted to the level of the FM
demodulator output (see Fig.16).
1997 Feb 126
Fig.3 Pin configuration for TEA6820T (top view).
A 3rd order low-pass filter (f
= 90 kHz) at the MPX input
g
provides an extra 190 kHz ACI suppression.
An interference gate is connected at the MPX demodulator
outputs. For AM the VCO is switched off.

Notes to the characteristics
1. For typical adjusting range see Figs 10 and 13.
2. For typical curve see Fig.11.
3. The static mute voltage follows the unweighted voltage level as function of FM-IF2 voltage and level adjustment
voltage V
. It additionally depends on multi-path level, noise (adjacent channel interferences) and the position of
38-4
TSWITCH (pin 3). For typical curve for mute voltage dependence see Fig.12.
4. The mono/stereo blend voltage is generated as a function of FM-IF2 voltage, multi-path level, noise and position of
TSWITCH.
5. The high-cut control voltage is generated as a function of FM-IF2 voltage, multi-path level, noise and position of
TSWITCH.
6. f

7. The AM oscillator signal is generated by division of the 61.5 MHz crystal oscillator. Two divider ratios programmable
by the I2C-bus: divide by 6 (AM-IF1= 10.7 MHz); divide by 2 (AM-IF1= 30 MHz).

I2C-BUS AND I2C-BUS CONTROLLED FUNCTIONS
2
C-bus specification
I
The standard I2C-bus specification is expanded by the
following definitions.
Structure of the I2C-bus logic: slave transceiver with auto
increment and expansion to switch a direct transfer of all
transmissions to an output for the radio front-end IC
(TEA6810T respectively TEA6811T).
Subaddresses are not used.
ATA TRANSFER FOR THE TEA6820T AND THE TEA6822T
D
Data sequence:
• Address
• Byte 1
• Byte 2.
The data transfer maybe in this order only. The transfer
direction of the data bytes is defined by the LSB of the
address.
The data becomes valid at the output of the internal
latches with the acknowledge of each byte. 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
• If the transfer of a byte was not completed, this byte is
lost and the previous information is available.
D
ATA TRANSFER TO AN OUTPUT OF THE FRONT-END IC
A data bit in the transceiver of the TEA6820T or TEA6822T
enables or disables a direct transfer of all transmissions to
an interface stage for the front-end IC.
For a transmission to the front-end IC the address and the
data format of the front-end IC has to be used.
Remark: the pull-up resistors for the front-end interface
(pins 6 and 7) should not be connected to the 5 V supply
voltage of the front-end IC, otherwise a bus pull-down
(pin 53) can occur during switching off the front-end supply
when the interface stage is enabled.
ATA TRANSFER TO THE IF IC
D
Data transfer to the IF IC (TEA6820T or TEA6822T) is
independent of the state of interface stage for the front-end
IC.

AM counting windows are 4 or 40 ms. FM counting windows are 4 or 40 ms. AM counting resolution is 250 or 25 Hz.
FM counting resolution is 5 kHz, 625 Hz, 50 kHz or 6.25 kHz. AM IF-prescaler is divisible by 1. FM IF-prescaler is
divisible by 25 or 200.

Note
1. In position FM with a prescaler ratio of 25, counter window of 40 ms and in position AM with 40 ms counter window
ambiguous counting results within the IF filter bandwidth are obtained. The counting range is 127 counts above and
127 counts below the nominal IF of 10.7 MHz for FM and 450 kHz for AM.
The IF count windows are valid for a crystal oscillator frequency of 61.5 MHz.
The FM/AM switching is carried out by bit 0 of byte 2 of the received data of the IC.
The IF counter operates continuously.
The IF counter and window-counter will be reset when the I2C-bus logic detects the address of the IC. This disables
changes in the latches for the IF count, while reading this value. If the transmission to the front-end IC is disabled after
the synthesizer loop of the TEA6810T/TEA6811T front-end IC has locked for a new frequency, the IF-count will be
available after the set measuring time.
The IF counter starts at 0. The IF counter output are the 8 least significant bits of the counting result.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
Reflow soldering
Reflow soldering techniques are suitable for all VSO
packages.
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.
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
(order code 9398 652 90011).
Wave soldering
Wave soldering techniques can be used for all VSO
packages if the following conditions are observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream end.
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.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Repairing soldered joints
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
