TMDS Regenerator
The ISL54105A is a high-performance TMDS timing
regenerator containing a programmable equalizer and a
clock data recovery (CDR) function for each of the 3 TMDS
pairs in an HDMI or DVI signal. The TMDS data outputs of
the ISL54105A are regenerated and perfectly aligned to the
regenerated TMDS clock signal, creating an extremely
clean, low-jitter DVI/HDMI signal that can be easily
decoded by any TMDS receiver.
The ISL54105A can be used as a cable extender, to clean
up a noisy/jittery TMDS source, or to provide a very stable
TMDS signal to a finicky DVI or HDMI receiver.
