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 opera-
tion. 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 1V_pp video signals.
Each channel includes an output amplifier capable of
driving a single (150Ω) 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.
