Frame Synchronization
LOGIC’s video products provide with a simple solution for video stream synchronization,
a key requirement in a number of applications, without the need
for implementing awkward (and costly) glue-logic.
When processing a video feed from a remote source,
such as a satellite feed, which exhibits phase and frequency wander
– it must often be aligned and timed to a reference clock
prior to downstream processing. In other words, the feeds’
timing must be synchronized or locked to a reference timing or
clock domain. This requires each incoming video frame to be written
into a video FIFO by the ‘remote’
clock domain and effectively delayed by some amount of time before
being released (or read out) via the reference timing and clock
domain.
LOGIC’s video products provides an immediate, off-the-shelf frame buffering
solution for synchronization - allowing engineers to spend more
time on product differentiation and less time juggling frames.
