NJM2583A
6CH VIDEO AMPLIFIER WITH SD/ HD LPF
Q GENERAL DESCRIPTION
The NJM2583A is a single supply voltage 6ch Video amplifier.
It includes LPF, Y/C MIX circuit and SDC interface. LPF for the
component signal can select SD/HD.
The NJM2583A is suitable for DVD recorder, set top box and
the high quality AV systems with the SD/HD output.

2. Shorten the feedback loop of an output coupling capacitor and the SAG correction capacitor of the video signal
output and put a 75Ω series resistance near IC pin.
3. Two-line driving circuit
This circuit drives two-line of 150Ω. However, it may cause to lose synchronization by an input signal of large
APL change (100% white signals more than 1Vp-p). Confirm the large APL change waveform (100% white
signals more than 1Vp-p) and evaluate sufficiently.
