Single Supply Video Driver with Reconstruction Filter and Charge Pump

The ISL59831 is a single supply video driver with reconstruction filter and charge pump. It is designed to drive SDTV displays with luma (Y) or composite video (CV) signals. It operates on a single supply (3.0V to 3.6V) and generates its own negative supply (-1.9V) using a regulated charge pump. Input signal can be AC or DC coupled. When AC coupled, the sync tip clamp sets the blank level to ground at the output, ensuring that the sync-tip voltage level is set to approximately -300mV at the back-termination resistor of a standard video load.
