SGM9115
Triple, 9MHz, 3rd-Order
SDTV Video Filter Driver
PRODUCT DESCRIPTION
SGM9115 is a video buffer which integrates triple 6dB
gain rail-to-rail output drivers and triple 3rd-order output
reconstruction filters with a -3dB bandwidth of 9MHz
and 44V/µs slew rate. Operating from single power
supply ranging from 3.3V to 5.5V, the SGM9115
provides improved image quality compared with
passive LC filters and discrete drivers solution.
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
(75Ω) loads.
The SGM9115 is available in Green SOIC-8 package
and ESD (HBM) reaches 8KV.
