SGM9115
Triple, 9MHz, 3rd Order
SDTV Video Filter Drivers
PRODUCT DESCRIPTION
SGM9115 is a video buffer which integrates triple 6dB
Gain rail-to-rail output driver and triple 3rd output
reconstruction filter, it has 9MHz -3dB bandwidth and
44V/µs slew rate. SGM9115 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
6.8mA quiescent current, the SGM9115 is ideally
suited for battery powered applications.
SGM9115 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. SGM9115 also integrates an internal level
shift circuit which avoids sync-pulse being clipped
and allows DC-coupled output. The drivers in
SGM9115 can drive DC or AC-coupled single (150Ω)
or dual (75 Ω) loads.
The SGM9115 has lead (Pb) free SOIC-8 package and
ESD(HBM) reaches 8KV.
