The ISL54100AHDMI-EVALZ (4:1) and ISL54105ACRZ-EVALZ (1:1) high-performance TMDS signal multiplexer/regenerator/retimer evaluation kits are used to evaluate the ISL54100A and ISL54105A TMDS regenerators.

The high performance TMDS (transition minimized differential signaling) ISL54100A timing regenerator and multiplexer and ISL54105A timing regenerator contain a programmable equalizer and a clock data recovery (CDR) function for each of the three TMDS pairs in an HDMI or DVI signal.

The TMDS data outputs of the ISL54100A and 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.
