Preliminary specification
Multistandard VIF-PLL and
FM-PLL demodulator
TDA9806
Notes

Values of video and sound parameters are decreased at V
P
= 4.5 V.
This parameter is not tested during production and is only given as application information for designing the
television receiver.
Loop bandwidth BL = 60 kHz (natural frequency f
n
= 15 kHz; damping factor d = 2; calculated with sync level within
gain control range). Resonance circuit of VCO: Q

f = 1 MHz (VCO frequency offset related to picture carrier frequency); white picture
video modulation.
V
i IF
signal for nominal video signal.
Offset current measured between pin 7 and half of supply voltage (V
P
= 2.5 V) under the following conditions: no
input signal at VIF input (pins 1 and 2) and VIF amplifier gain at minimum (V
28
= V
P
).
Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth BL = 60 kHz:
a) modulation VSB; sound carrier
off
; f
video
> 0.5 MHz.
b) sound carrier
on
; f
video
= 10 kHz to 10 MHz.
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
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
μ
A 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”
