SGM9123 Datasheet | SG Micro

DESCRIPTION SGM9123 is a video buffer which integrates triple 6d B Gain rail-to-rail output driver and triple 3rd output reconstruction filter, it has 8MHz -3d B bandwidth and 44V/µs slew rate. SGM9123 provides improved image quality pared with passive LC filters and discrete drivers solution. Operating from single supplies ranging from +2.5V to +5.5V and sinking an ultra-low .. 7.4m A 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 package and ESD (HBM) reaches 8KV. - - - - - - - - - Triple, 8MHz, 3rd Order SDTV Video Filter Drivers FEATURES Triple 3rd order 8MHz (SD) Filters Transparent Input Clamping 6d B Output Driver Gain and Drive Dual Video Load Rail-to-Rail Output Input Voltage Range Includes Ground AC or DC Coupled Inputs AC or DC Coupled Outputs Operates from 2.5V to 5.5V Single Power Supply Low Power (2.5m A/channel) 7.4m A Total Supply Current - Lead (Pb) Free SO-8 Package APPLICATIONS Video Amplifiers Cable and Satellite Set Top Boxes munications Devices Video on Demand Portable and Handheld Products Personal Video Recorders DVD Players SDTVs BLOCK DIAGRAM SG Microelectronics Co, Ltd Tel: 86/10/51798160/80 .sg-micro.
