NJM2570A
75 Driver with Filter and Y/C MIX
s GENERAL DESCRIPTION NJM2570A is a video amplifier included LPF in Y and C system. Adjustable LPF characteristic with external resistor and output with 75ohm driver optimize the TV monitor system. Also, it can discriminated the aspect ratio of TV by internal DC interface for S terminal. NJM2570A includes power save circuit to suitable for portable video application. s PACKAGE OUTLINE
