PRELIMINARY `  DESCRIPTION  FEATURES Agamem Microelectronics Inc. AA8672 Low Voltage Video Amplifier With Coaxial Communication Receiver AA8672 is a video driver which integrates 6dB gain rail to rail output driver, 3 low pass filter and coaxial communication receiver. The VREF (pin8) can set the threshold voltage of the receiver by external circuit. It supports +2.5V and +5.5V operating voltage, and is ideal for video output device such as surveillance camera. The AA8672 can be DC-coupled or AC-couple with input video signal, such as the output stage of DAC to eliminate out-of-band noise. The output can drive DC-couple or AC-couple signal (150Ω) or dual (75Ω) loads. rd • Operating Voltage, +2.5V~+5.5V • Transparent Input Clamping • 3 Order 72MHz (Full HD) Filter rd • 6dB Output Driver Gain and Drive Dual Video Load • Rail-to-Rail Output • AC or DC-coupled Inputs • AC or DC-coupled Outputs • High Speed Coaxial Communication Receiver • MSOP8 package  APPLICATIONS • Cable and Satellite Set-Top Boxes • Portable and Handheld Products • Personal Video Recorders • AHD/TVI/CVI Analog HD Camera  BLOCK DIAGRAM ©Copyright Agamem Microelectronics Inc. 1 www.agamem.com.tw 2016/04/18 Ver 1.0 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
