SGM9123
Triple, 8MHz, 3rd Order
SDTV Video Filter Drivers
GENERAL DESCRTPTION
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 pa
