SDTV Video Filter Drivers

GENERAL DESCRIPTION

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.

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.

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

ESD (HBM) reaches 8KV.
