CMOS IC
TRIPLE VIDEO DRIVER
WITH SELECTABLE
HD/SD VIDEO FILTERS
FOR RGB OR YUV
SIGNALS
DESCRIPTION
The UTC
VF8418
consists of a triple 6
th
order filter with
selectable 30MHz or 8.0MHz frequencies. The triple filters are
intended for either YUV or RGB signals. There is a 2-to-1
multiplexer in each filter channel. 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 UTC
VF8418
offers comprehensive filtering for cable
set-top boxes, satellite set-top boxes, HDTV, video on demand
(VOD), personal video recorders, or DVD applications.
FEATURES
* Three video anti-aliasing or reconstruction filters
* 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
* Drives single, +6dB output AC coupled 150Ω loads
* 0.6% differential gain with 0.15° differential phase
* 36dB/octave roll-off on all channels

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Functional operation under any of these conditions is NOT implied. Performance and reliability are
guaranteed only if operating conditions are not exceeded.
