SGM9115 Triple, 9MHz, 3rd-Order SDTV Video Filter Driver

GENERAL 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.
