TMDS Regenerators with Multiplexers

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.

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.
