DAC

STw8009/STw8019 outputs generate Composite video signal on one output or Y/C video

signals on two outputs.

Two embedded 10-bit DACs allow the STw8009/STw8019 to directly drive 37.5 Ohms loads

on each output.

4.12

Power management

Power management includes power supplies, reset signals, clock gating and a set of

dedicated pins and registers. Power management is used to set the STw8009/STw8019 in

different operating modes.
