NJM2525 4CH VIDEO AMPLIFIER WITH SW&SD/ HD LPF ■ GENERAL DESCRIPTION The NJM2525 is 4ch video amplifier with SD/HD LPF. The NJM2525 includes 2in-1out selector for the composite and component signal. The isolation amplifier eliminates the common mode noise from external equipment. The NJM2525 is suitable for the AV equipment such as the home theater systems and AV receivers that switch the internal Video signal and the external Video signal. ■ FEATURES ● Operating Voltage ● SD/ HD LPF ● 6dB amplifier ● 75Ω Driver Circuit ● Y/C MIX Circuit ● Isolation amplifier ● Power Save Circuit ● Bipolar Technology ● Package Outline ■ PACKAGE OUTLINE NJM2525V 4.5 to 5.5V 6.75MHz/ 13.5MHz/ 30MHz SSOP32 ■ BLOCK DIAGRAM VCC1 PS1 PS2 VCC2 VCC3 SCIN BIAS 6dB MIX 6dB 75ΩDRV VOUT 6.75M SYIN CLAMP 13.5M YIN1 6dB 75ΩDRV YOUT 30M CLAMP 13.5M PbIN1 6dB 75ΩDRV PbOUT 30M BIAS 13.5M PrIN1 6dB 75ΩDRV PrOUT 30M BIAS CLV2 VIN CLAMP BIAS CLV1 VING BIAS CLY2 YIN2 CLAMP BIAS CLY1 YING BIAS PbIN2 BIAS PbING BIAS PrIN2 BIAS PrING BIAS GND1 LPFSW SLSW GND2 (input1 or input2) (13.5M or 30M) GND3 Ver.1.3 -1- NJM2525 !
