SGM9123

Features

Product Name: Triple 8MHz 3rd Order SDTV Video Filter Drivers 8MHz three-channel video driver

Product model: SGM9123

Product 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 (75Ω) loads.

The SGM9123 has Green SOIC-8 package and ESD (HBM) reaches 8KV
