描述
The ISL54100A is a high-performance transition minimized differential signaling (TMDS) timing regenerator and multiplexer. The receiver contains 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 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 ISL54100A's design and package footprint support 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 device is 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 HDMI 1.3 audio formats and options.
