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 selectable frequency
response of 8, 16, or 32MHz. The filters can also be bypassed
for high-frequency operation. Additional functionality of these
channels include input biasing mode and output disable.
The FMS6203 may be driven directly by a DC-coupled DAC out-
put 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.
