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 = 75 kHz (natural frequency f
n
= 11 kHz; damping factor d
≈
3.5; calculated with sync level within
gain control range). Resonance circuit of VCO: Q

signal for nominal video signal.
Measurements taken with SAW filter G3962 (sound carrier suppression: 40 dB); loop bandwidth BL = 75 kHz:
a) Modulation VSB; sound carrier

> 0.5 MHz.
b) Sound carrier

; SIF SAW filter G9353; 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 (between pin 18 and pin 19).
The leakage current of the AGC capacitor should not exceed 1
μ
A. Larger currents will increase the tilt.
10. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value), on pin 8. B = 5 MHz
weighted in accordance with “CCIR 567”
