Featuring 12-bit A-to-D and adaptive decoding,
the 8960DEC provides broadcast-quality serial
component digital video to help transition
from an analog to a digital facility. A unique
capability of the 8960DEC is that by adding the
8900FSS frame sync sub-module you get a full
frame synchronizer or a frame delay.
