SDTV Video Filter Drivers

SGM9123

GENERAL DESCRIPTION

FEATURES

SGM9123 is a video buffer which integrates triple 6dB

Gain rail-to-rail output driver and triple 3rd output

reconstruction filter, it has 8MHz -3dB bandwidth and

44V/µs slew rate. SGM9123 provides improved image

quality compared with passive LC filters and discrete

drivers solution. Operating from single supplies

ranging from +2.5V to +5.5V and sinking an ultra-low

7.4mA quiescent current, the SGM9123 is ideally

suited for battery powered applications.

• Triple 3rd order 8MHz (SD) Filters

• Transparent Input Clamping

• 6dB Output Driver Gain and Drive Dual Video Load

• Rail-to-Rail Output

• Input Voltage Range Includes Ground

• AC or DC Coupled Inputs

• AC or DC Coupled Outputs

• Operates from 2.5V to 5.5V Single Power Supply

• Low Power (2.5mA/channel)

7.4mA Total Supply Current

• Lead (Pb) Free SO-8 Package

SGM9123 can be DC-coupled or AC-coupled with

input video signal, such as the output stage of DAC to

eliminate out-of-band noise. Internal diode clamps

and bias circuitry may be used if AC-coupled inputs

are required. SGM9123 also integrates an internal

level shift circuit which avoids sync-pulse being

clipped and allows DC-coupled output. The drivers in

SGM9123 can drive DC or AC-coupled single (150Ω)

or dual (75 Ω) loads.

APPLICATIONS

Video Amplifiers

Cable and Satellite Set Top Boxes

Communications Devices

Video on Demand

Portable and Handheld Products

Personal Video Recorders

DVD Players

The SGM9123 has lead (Pb) free SO-8 package and

ESD (HBM) reaches 8KV.
