Description
The FMS6417A offers comprehensive filtering for set top box or
DVD applications. This part consists of a triple 6th order filter
with selectable 30MHz or 8MHz frequencies and a dual filter for
filtering Y,C with a composite summer and a modulator channel
with sound-notch and FCC group delay compensation. The
modulator provides sound-notching and FCC group delay com-
pensation for NTSC.
2-to-1 multiplexers are provided on the triple filters as well as
provisions for auxiliary inputs to the composite channel. The triple
filters are intended for either YUV or RGB signals. All channels
accept AC or DC coupled ground-referenced 1V signals. The filters
output 2V
pp
signals into AC coupled terminated loads. The low-
pass filters are powered by 3.3V and the modulator and outputs
by 5.0V.
