FMS6303 Low-Cost, 3-Channel, Video Filter Driver for SD/ED/HD (1080i)/HD (1080P)
... The FMS6303 outputs are DC offset from the input by 150mV; therefore, VOUT = 2•VIN DC+150mV. This offset is required to obtain optimal performance from the output driver and is held at the minimum value to decrease the standing DC current into the load. Since the FMS6303 has a 2x (6dB) gain, the out ...
