Description
The FMS6418A offers comprehensive filtering for set top
box or DVD applications. This part consists of a triple 6th
order filter with selectable 30MHz or 8.0MHz frequencies.
A 2-to-1 multiplexer is provided on each filter channel. The
triple filters are intended for either YUV or RGB signals. All
channels accept DC coupled ground-referenced 1V signals.
The filters provide 2Vpp signals into AC coupled terminated
loads. The low-pass filters are powered by 3.3V and the out-
puts by 5.0V.
The FMS6418A is available in both 16-pin SOIC and 14-pin
TSSOP packages.
