SGM9127 4-Channel, 5th-Order, Standard Definition Video Filter Driver

GENERAL DESCRIPTION

The SGM9127 is a low voltage, 4-channel video amplifier with integrated reconstruction filters and input clamps. Specially suited for standard definition video signals, this device is ideal for a wide range of television and set-top box applications.

SGM9127 offers 6dB gain rail-to-rail output driver and 5th-order output reconstruction filter on all four channels. It has 8MHz -3dB bandwidth and 35V/μs slew rate. SGM9127 provides improved image quality compared with passive LC filters and discrete drivers solution. Operating from single power supply ranging from 3.3V to 5.5V and sinking an ultra-low 30mA quiescent current, the SGM9127 is ideally suited for battery powered applications.

SGM9127 can be DC-coupled or AC-coupled with input video signal, such as the output stage of DAC to eliminate out-of-band noise. The output in SGM9127 can be configured as DC- or AC-coupled output.

The SGM9127 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40 to +85.
