TSH122 Video Line Driver The STMicroelectronics single-channel video line driver is optimized for driving CVBS signals from battery-powered applications to a TV via a 75 ohm line without additional external components. The TSH122 integrates a 6 dB-gain buffer, a 6th-order internal reconstruction filter to attenuate the parasitic frequency of 27 MHz from the clock of the video DAC, a rail-to-rail output, and other features. The STMicroelectronics TSH122 video line driver operates from 2.25V to 5V single power supplies and is tested at 2.5V and 3.3V.
