MAX3815

TMDS Digital Video Equalizer for DVI/HDMI Cables

Cable Equalizer IC Extends DVI/HDMI Reach Beyond 30m


Please check latest availability status for a specific part variant.

Description

The MAX3815 cable equalizer automatically provides compensation for DVI™, HDMI™, DFP, PanelLink®, and ADC cables. It extends the usable cable distance up to 36 meters. The MAX3815 is designed to equalize signals encoded in the transition-minimized differential signaling (TMDS®) format.

The MAX3815 features four CML-differential inputs and outputs (three data and one clock). It provides a loss-of-signal (LOS) output that indicates loss-of-clock signal. The outputs include a disable function or the equalizer can be powered down to conserve power. For direct chip-to-chip communication, the output drivers can be switched to one-half the DVI output specification to conserve power and reduce EMI. Equalization can be automatic or set to manual control for specific in-cable applications.

The MAX3815 is available in a 7mm x 7mm, 48-pin TQFP-EP package and operates over a 0°C to +70°C temperature range.
