Notes
1. Video and sound parameters are degraded at V
2. This parameter is not tested during production and is provided as application information for use in designing the
3. Loop bandwidth BL = 70 kHz (natural frequency f
4. Temperature coefficient of external LC circuit is equal to zero.
5. V
6. V
7. The leakage current of the AGC capacitor should not exceed 1 A to avoid larger tilt.
8. S/N is the ratio of black-to-white amplitude to the black level noise voltage (RMS value, pin 13). B = 5 MHz weighted
9. The intermodulation figures are defined:
10. Measurements taken with SAW filter G1962 (sound shelf: 20 dB); loop bandwidth = 70 kHz.
11. Response speed valid for a VIF input level range of 200 V up to 70 mV.
12. A current source output is provided to match the AFC output signal to different tuning systems. The test circuit is
13. Depending on the ratio C/C
