Description
The FMS6418B offers comprehensive filtering for set-top box or
DVD applications. This part consists of a triple 6th order filter
with selectable 32MHz or 8MHz frequencies.
A 2-to-1 multiplexer is provided on each filter channel. The triple
filters can accomodate either YUV, RGB, or YPbPr signals. All
channels accept DC coupled ground-referenced 1V signals.
The filters provide 2V_pp signals into AC coupled terminated
loads. The low-pass filters are powered by 3.3V and the outputs
by 5.0V.
The FMS6418B is available in both 16-pin SOIC and 14-pin
TSSOP packages.
