Description
The FMS6203 offers comprehensive filtering for set-top box or DVD applications. It is intended to replace passive LC filters and drivers with a low-cost integrated device. Filter channels are specialized for either component (YPbPr) or RGB video signals. These channels offer a selectable frequency response of 8, 16, or 32MHz. The filters can also be bypassed for high-frequency operation. Additional functionality of these channels includes input biasing mode and output disable. The FMS6203 may be driven directly by a DC-coupled DAC output or an AC-coupled signal. All inputs accept standard 1Vpp video signals. Each channel includes an output amplifier capable of driving a single (150) AC- or DC-coupled video load. All outputs can be disabled to save power in DC-coupled applications. The device is available in two factory-set options, a 0dB gain option and a 6dB gain option.

Applications
Cable and Satellite Set-Top Boxes DVD Players HDTV Personal Video Recorders (PVR) Video On Demand (VOD)
