The MAX3815ACCM+T is a TMDS digital video equalizer for HDMI/DVI cables in 48 pin TQFP package. The MAX3815A cable equalizer automatically provides compensation for DVI and HDMI v1.3 cables. It extends the usable cable distance up to 40meters (1.65Gbps) and 35meters (2.25Gbps). The MAX3815A is designed to equalize signals encoded in the transition minimized differential signalling (TMDS) format. It 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. Upon LOS, the chip is powered down. 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. The output drive current can also be increased to allow the use of back termination resistors for improved signal integrity. Equalization can be automatic or set to manual control for specific in-cable applications.
