TDA9806

FUNCTIONAL DESCRIPTION
Vision IF amplifier

The vision IF amplifier consists of three AC-coupled
differential amplifier stages. Each differential stage
comprises a feedback network controlled by emitter
degeneration.

Tuner and VIF AGC

The AGC capacitor voltage is transferred to an internal IF
control signal, and is fed to the tuner AGC to generate the
tuner AGC output current (open-collector output). The
tuner AGC takeover point can be adjusted. This allows the
tuner and the SWIF filter to be matched to achieve the
optimum IF input level.

The AGC detector charges/discharges the AGC capacitor
to the required voltage for setting of VIF and tuner gain in
order to keep the video signal at a constant level.
Therefore for negative video modulation the sync level of
the video signal is detected.

Frequency Phase Locked Loop detector (FPLL)

The VIF-amplifier output signal is fed into a frequency
detector and into a phase detector via a limiting amplifier.
During acquisition the frequency detector produces a DC
current proportional to the frequency difference between
the input and the VCO signal. After frequency lock-in the
phase detector produces a DC current proportional to the
phase difference between the VCO and the input signal.
The DC current of either frequency detector or phase
detector is converted into a DC voltage via the loop filter,
which controls the VCO frequency.

VCO, travelling wave divider and AFC

The VCO operates with a resonance circuit (with L and C
in parallel) at double the PC frequency. The VCO is
controlled by two integrated variable capacitors. The
control voltage required to tune the VCO from its
free-running frequency to actually double the PC
frequency is generated by the Frequency-Phase detector
and fed via the loop filter to the first variable capacitor
(FPLL). This control voltage is amplified and additionally
converted into a current which represents the AFC output
signal. At centre frequency the AFC output current is equal
to zero.

The oscillator signal is divided-by-two with a Travelling
Wave Divider (TWD) which generates two differential
output signals with a 90 degree phase difference
independent of the frequency.

Video demodulator and amplifier

The video demodulator is realized by a multiplier which is
designed for low distortion and large bandwidth. The vision
IF input signal is multiplied with the ‘in-phase’ signal of the
travelling wave divider output.

The demodulator output signal is fed via an integrated
low-pass filter for attenuation of the carrier harmonics to
the video amplifier. The video amplifier is realized by an
operational amplifier with internal feedback and high
bandwidth. A low-pass filter is integrated to achieve an
attenuation of the carrier harmonics. The video output
signal is 1 V (p-p) for nominal vision IF modulation.

Video buffer

For an easy adaption of the sound traps an operational
amplifier with internal feedback is used. This amplifier is
featured with a high bandwidth and 7 dB gain. The input
impedance is adapted for operating in combination with
ceramic sound traps. The output stage delivers a nominal
2 V (p-p) positive video signal. Noise clipping is provided.

Intercarrier mixer

The intercarrier mixer is realized by a multiplier. The VIF
amplifier output signal is fed to the intercarrier mixer and
converted to intercarrier frequency by the regenerated
picture carrier (VCO). The mixer output signal is fed via a
high-pass for attenuation of the video signal components.

FM-PLL demodulator

TDA9806

FM detector

The FM detector consists of a limiter, an FM-PLL and an
AF amplifier. The limiter provides the amplification and
limitation of the FM sound intercarrier signal before
demodulation. The result is high sensitivity and AM
suppression. The amplifier consists of 7 stages which are
internally AC-coupled in order to minimize the DC offset
and to save pins for DC decoupling.

The FM-PLL consists of an integrated relaxation oscillator,
an integrated loop filter and a phase detector. The
oscillator is locked to the FM intercarrier signal, output
from the limiter. As a result of locking, the oscillator
frequency tracks with the modulation of the input signal
and the oscillator control voltage is superimposed by the
AF voltage. The FM-PLL operates as an FM-demodulator.

The AF amplifier consists of two parts:

1. The AF preamplifier for FM sound is an operational
amplifier with internal feedback, high gain and high
common mode rejection. The AF voltage from the PLL
demodulator, by principle a small output signal, is
amplified by approximately 33 dB. The low-pass
characteristic of the amplifier reduces the harmonics of
the intercarrier signal at the sound output terminal, at
which the de-emphasis network for FM sound is
applied. An additional DC control circuit is
implemented to keep the DC level constant,
independent of process spread.

2. The AF output amplifier (10 dB) provides the required
output level by a rail-to-rail output stage. This amplifier
makes use of an input selector for switching to FM
de-emphasis or mute state, controlled by the mute
switching voltage.

Internal voltage stabilizer and

1

⁄2VP-reference

The bandgap circuit internally generates a voltage of
approximately 1.25 V, independent of supply voltage and
temperature. A voltage regulator circuit, connected to this
voltage, produces a constant voltage of 3.6 V which is
used as an internal reference voltage.

For all audio output signals the constant reference voltage
cannot be used because large output signals are required.
Therefore these signals refer to half the supply voltage to
achieve a symmetrical headroom, especially for the
rail-to-rail output stage. For ripple and noise attenuation
the

1

⁄2VPvoltage has to be filtered via a low-pass filter by

using an external capacitor together with an integrated
resistor (fg= 5 Hz). For a fast setting to 1⁄2VP an internal
start-up circuit is added.

Notes

1. Values of video and sound parameters are decreased at VP= 4.5 V.

2. This parameter is not tested during production and is only given as application information for designing the
television receiver.

3. Loop bandwidth BL = 60 kHz (natural frequency fn= 15 kHz; damping factor d = 2; calculated with sync level within
gain control range). Resonance circuit of VCO: Q0> 50; C

7. Offset current measured between pin 7 and half of supply voltage (VP= 2.5 V) under the following conditions: no
input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V28=VP).

8. Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth BL = 60 kHz:
a) modulation VSB; sound carrier off; f

> 0.5 MHz.

b) sound carrier on; f

= 10 kHz to 10 MHz.

9. The 7 dB buffer gain accounts for 1 dB loss in the sound trap. Buffer output signal is typical 2 V (p-p), in event of
CVBS video amplifier output typical 1 V (p-p). If no sound trap is applied a 330 Ω resistor must be connected from
output to input (from pin 21 to pin 22).

10. The leakage current of the AGC capacitor should not exceed 1 µA at B/G standard. Larger currents will increase
the tilt.

11. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 10). B = 5 MHz weighted
in accordance with

“CCIR 567”

.

12. The intermodulation figures are defined:

14. To match the AFC output signal to different tuning systems a current source output is provided. The test circuit is
given in Fig.6. The AFC-steepness can be changed by the resistors at pin 23.

15. Depending on the ratio ∆C/C0 of the LC resonant circuit of VCO (Q0> 50; see note 3; C0=C

int+Cext

).

16. The intercarrier output signal at pin 20 can be calculated by the following formula taking into account the video output
signal at pin 21 (V

o video(p-p)

= 1 V typical) as a reference:

with = correction term for RMS value,

= sound-to-picture carrier ratio at VIF input (pins 1 and 2) in dB,

6 dB = correction term of internal circuitry
and ±3 dB = tolerance of video output and intercarrier output amplitude V

o(rms)

.

Example: SAW filter G1962 (sound shelf: 20 dB) ⇒⇒ V

o(rms)

= 32 mV typical.

17. Input level for second IF from an external generator with 50 Ω source impedance. AC-coupled with 10 nF capacitor,
f

mod

= 1 kHz, 27 kHz (54% FM deviation) of audio references. A VIF input signal is not permitted. Pin 28 has to be
connected to positive supply voltage for minimum IF gain. S/N and THD measurements are taken at 50 µs
de-emphasis.

a) Second IF input level 10 mV RMS.

18. Measured with an FM deviation of 27 kHz the typical AF output signal is 500 mV (RMS) (Rx=0Ω; see Fig.10).
By using Rx= 470 Ω the AF output signal is attenuated by 6 dB (250 mV RMS). For handling an FM deviation of
more than 53 kHz the AF output signal has to be reduced by using Rx in order to avoid clipping (THD < 1.5%).
For an FM deviation up to 100 kHz an attenuation of 6 dB is recommended with Rx= 470 Ω.

19. The leakage current of the decoupling capacitor (2.2 µF) should not exceed 1 µA.

20. For all S/N measurements the used vision IF modulator has to meet the following specifications:
a) Incidental phase modulation for black-to-white jump less than 0.5 degrees.
b) Picture-to-sound carrier ratio; PC/SC = 13 dB (transmitter).
c) Sound shelf of VIF SAW filter: minimum 20 dB.

21. Measurements taken with SAW filter K6256 (Siemens) for vision and sound IF (sound shelf: 20 dB). Input level
V

i SIF

= 10 mV (RMS), 27 kHz (54% FM deviation).

22. The PC/SC ratio at pins 1 and 2 is calculated as the addition of TV transmitter PC/SC ratio and SAW filter PC/SC
ratio. This PC/SC ratio is necessary to achieve the S/N (W) values as noted. A different PC/SC ratio will change
these values.

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”

(order code 9398 652 90011).

Soldering by dipping or by wave

The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

Repairing soldered joints

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.
