TRIPLE VIDEO DRIVER WITH SELECTABLE HD/SD VIDEO FILTERS FOR RGB OR YUV SIGNALS
DESCRIPTION
The UTC VF8418 consists of a triple 6th
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
