Abstract :
High-definition multimedia interface (HDMI1.3) specifies video serial link that operates from as low as 250 Mb/s to 3.4 Gb/s with coverage over different multimedia data formats. Wide-spread consumer adoption of the new HDMI standard demands receivers that reliably reproduce the incoming data stream under conditions of either short/long cables or clear/fuzzy signal. In many cases, input video signal could be quite smeared and noisy when a cheap cable is used for cost saving. To satisfy the wide range of operation conditions, the presented HDMI receiver adaptively adjusts its loop frequency response with respect to the stream-in data rate and with an adaptive equalizer in front.
