DATA SHEET
FMS6418A
General Description
The FMS6418A offers comprehensive ltering for set top
box or DVD applications. This part consists of a triple 6th
order lter with selectable 30MHz to 8.0MHz frequencies.
A 2-to-1 multiplexer is provided on each lter. The lters
are intended for either YUV or RGB signals. All channels
accept DC coupled ground-referenced 1V signals. The
lters provide 2Vpp signals into AC coupled terminated
loads. All channels provide 6dB gain, accept 1V ground
referenced inputs, and drive AC coupled loads. The RGB
low-pass lters are powered by 3.3V and the output buffers
are powered by 5.0V.
The FMS6418A is a next generation lter solution from
Fairchild Semiconductor addressing the expanding ltering
needs for set top boxes, and DVD players. The product
provides selectable ltering with cutoff frequencies of
30MHz or 8.0MHz on the RGB/YUV channels. Thus, the
FMS6418A addresses the requirement for a single set top
box to be compatible with a variety of resolution standards.
Multiplexers on the RGB channels provide further exibility.
For DVD, Set-top Box, and TV applications, the product
provides ltering and output drive amplication for three
channels of outputs (RGB/YUV).
Applications
DC Levels
At any given time, the input signal’s DC levels must be
between 0.0V and 1.3V to utilize the optimal headroom and
to avoid clipping on the outputs.
Single Supply +5V Operation
For low power consumption, the FMS6418 was designed to
operate off of 5V and 3.3V. VCCA can be operated from 5V
instead of 3.3V and still meet specications, except power
consumption. When the 3.3V supply is increased to 5V, the
typical current consumption increases by 5mA. The net
effect is the part dissipates an additional 22 percent of power.
Driving the Digital Pins with 3.3V
or 5V Logic.
Either is allowed as long as the Vih and Vil are adhered to.
