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.
