NJM2570A

NJM2570A www.DataSheet4U.com 75Ω 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 NJM2570AV s FEATURES q Operating Voltage 4.5 to 5.5V q Input Y and C 0.5Vpp q Internal LPF 0dBtyp. at 4MHz (at IREF=33kΩ) -35dBtyp. at 10MHz (at IREF=33kΩ) 0dBtyp. at 6MHz (at IREF=22kΩ) -40dBtyp. at 16MHz (at IREF=22kΩ) q Internal DC Interface for aspect ratio discrimination q Bipolar technology q Package Outline SSOP16 s BLOCK DIAGLAM V+1 V+2 s PIN CONFIGURATION 1 16 8 9 1.
