The ISL54100, ISL54101, ISL54102 are high-performance
TMDS (Transition Minimized Differential Signaling) timing
regenerators and multiplexers. The receiver contains 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 ISL54100 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 ISL54100’s design and package footprint supports
many compound configurations. Two ISL54100s can create
a DualLink 4:1 mux, a 4:2 crosspoint, or an 8:1 mux.
Additional ISL54100s can create larger combinations of
these building blocks. The ISL54102 with its 2:1
multiplexing function serves applications with fewer inputs,
while the ISL54101 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 marginal DVI or HDMI receiver.
