Maxim Introduces the MAX3815A, a 2.25Gbps Automatic Cable Equalizer for HDMI v1.3 TMDS Applications
The MAX3815A is a 2.25Gbps automatic cable equalizer for HDMI v1.3 TMDS applications. The MAX3815A is capable of compensating for 0 to 35m of 24 AWG HDMI cable or 0 to 22m of 28 AWG HDMI cable, running TMDS data at rates up to 2.25Gbps. The device is compatible with HDTV resolutions of 720p, 1080i, 1080p, and 1080p with 30- to 36-bit color (”Deep Color”). It also supports VGA to WUXGA computer resolutions. The adaptive equalizer in each data channel automatically applies the optimum equalization needed to equalize the cable. A manual equalization mode is also available for specific in-cable applications. The MAX3815A features three differential data channels, one clock channel, and an LOS (loss-of-signal) output, which automatically squelches the outputs when a clock signal is not present. This device operates from a 3.3V supply and consumes 0.6W. Packaged in a lead-free, 7mm x 7mm, 48-pin TQFP, the MAX3815A is specified over the 0°C to +70°C commercial temperature range…
