Single standard VIF-PLL with QSS-IF and
FM-PLL demodulator
TDA9808
Notes to the characteristics
1.
Values of video and sound parameters are decreased at V
P
= 4.5 V.
2.
Level headroom for input level jumps during gain control setting.
3.
This parameter is not tested during production and is only given as an application information for designing the
television receiver.
4.
Loop bandwidth BL = 70 kHz (natural frequency f
n
= 12 kHz; damping factor d
≈
3; calculated with sync level within
gain control range). Resonance circuit of VCO: Q

≈
8.5 pF (loop voltage approximately
2.7 V).
5.
Temperature coefficient of external LC-circuit is equal to zero.
6.

8.
The leakage current of the AGC capacitor should not exceed 100 nA at M, N standard. Larger currents will increase
the tilt.
9.
S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 9). B = 5 MHz weighted
in accordance with “CCIR 567”
