The ISL54100A, ISL54101A, ISL54102A are highperformance 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

ISL5410xA 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 ISL5410xA’s design and package footprint supports

many compound configurations. Two ISL54100As can

create a DualLink 4:1 mux, a 4:2 crosspoint, or an 8:1 mux.

Additional ISL54100As can create larger combinations of

these building blocks. The ISL54102A with its 2:1

multiplexing function serves applications with fewer inputs,

while the ISL54101A 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.

Certified HDMI 1.3a compliant by the HDMI ATC for the

following features: 12 bit Deep Color (1080i/720p

guaranteed, 1080p typical), x.v.Color™, and all HDMI1.3

audio formats and options.
