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.
