FMS6418A
Triple Video Driver with Selectable HD/SD
Video Filters for RGB or YUV Signals
Features
Description
• Three video anti-aliasing or reconstruction filters
• YUV/RGB signal support
• 2:1 Mux inputs for multiple RGB/YUV inputs
• Selectable 8MHz or 30MHz 6th order filters
for SD/HD applications
• DC coupled input, AC coupled output
• All outputs can drive AC coupled 150Ω loads and
provide 6dB of gain
• 0.6% differential gain with 0.15° differential phase
• 36dB/octave roll-off on all channels
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.
Applications
The FMS6418A is available in both 16-pin SOIC and 14-pin
TSSOP packages.
• Cable Set top boxes
• Satellite Set top boxes
• DVD players
• HDTV
• Personal Video Recorders (PVR)
• Video On Demand (VOD)
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 outputs by 5.0V.

The FMS6418A is a next generation filter solution from
Fairchild Semiconductor addressing the expanding filtering
needs for set top boxes, and DVD players. The product
provides selectable filtering 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 flexibility.
For DVD, Set-top Box, and TV applications, the product
provides filtering and output drive amplification for three
channels of outputs (RGB/YUV).

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 specifications, 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.
