FMS6419
Selectable RGB (YUV) HD/SD Video Filter Driver
with Y, C, Composite Outputs
Features
• Three channel video reconstruction filters
• YUV/RGB filters
• 2:1 Mux inputs for multiple RGB/YUV inputs
• Selectable 8MHz or 30MHz 6th order filters
for RGB (YUV) applications
• 8MHz 6th order Y, C filters with composite summer
• DC coupled input, AC coupled output
• All outputs can drive AC coupled 150
Ω
loads and
provide 6dB of gain
• Dual multiplexed inputs
• 0.6% differential gain with 0.2° differential phase
• 36dB/octave roll-off on all channels
Description
The FMS6419 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.
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 out-
puts by 5.0V.
Applications
• Cable Set top boxes
• Satellite Set top boxes
• DVD players
• HDTV
• Personal Video Recorders (PVR)
• Video On Demand (VOD)
