General Description
The FMS6417A offers comprehensive ï¬ltering for set top box or
DVD applications. This part consists of a triple 6th order ï¬lter
with selectable 30MHz or 8MHz frequencies and a dual ï¬lter for
ï¬ltering 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
compensation for NTSC. 2-to-1 multiplexers are provided on
the triple ï¬lters as well as provisions for auxiliary inputs to the
composite channel. The triple ï¬lters are intended for either YUV
or RGB signals. All channels accept DC coupled ground-refer-
enced 1V signals. The ï¬lters output 2Vpp signals into AC coupled
terminated loads. The low-pass ï¬lters are powered by 3.3V and
the modulator and outputs by 5.0V.
The FMS6417A is a next generation ï¬lter solution from Fairchild
Semiconductor, addressing the expanding ï¬ltering needs for set
top boxes, and DVD players. The product provides selectable ï¬l-
tering from 30MHz or 8MHz on the RGB channels. Thus, the
FMS6417A addresses the requirement for a single set top box
to be compatible with a variety of resolution standards. Addi-
tionally, the product provides additional ï¬lters for Y, C, CV, and
modulator outputs. Multiplexers on the RGB and CV channel
provide further ï¬exibility.
For DVD applications, the product provides ï¬ltering and output
drive ampliï¬cation for 7 channels of outputs. These include R,
G, B, Y, C, CV, and modulator outputs.
For set top boxes, this product provides for 2 channels of video
to be ï¬ltered, as well as the ï¬exibility of selectable high order
ï¬ltering for multiple resolution standards. Additional ï¬exibility is
provided by the additional Y,C ï¬lterswith composite summers.
All channels provide 6dB gain, accept 1V ground referenced
inputs, and drive AC coupled loads. The ï¬lters for the R, G, B, Y,
C, and CV channels are powered from a 3.3V supply and the
modulator channel and outputs from 5V.
The modulator channel has sound-notch and FCC group delay
compensation set for NTSC speciï¬cations.
