Product specification
Digital video encoder
SAA7128AH; SAA7129AH
Notes
1.
2.
3.
At maximum supply voltage with highly active input signals.
The data is for both input and output direction.
If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
subcarrier frequency and line/field frequency.
Referring to peak-to-peak analog voltages resulting from identical peak-to-peak digital codes.
