NJM2570A 75Ω Ω Driver with Filter and Y/C MIX ■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE 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. ■ FEATURES ● Operating Voltage 4.5 to 5.5V ● Input Y and C 0.5Vpp ● 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) ● Internal DC Interface for aspect ratio discrimination ● Bipolar technology ● Package Outline SSOP16 Yin 14 CLAMP 6dB V+1 V+2 ■ BLOCK DIAGLAM 15 9 LPF 6dB 6dB 6dB Yout 10 Ysag 6 Vout 7 Vsag 5 Cout 4 SDCout ■ PIN CONFIGURATION 1 16 8 9 1.
