The MAX3815A cable equalizer automatically provides compensation for DVI™ and HDMI™ v1.3 cables. It extends the usable cable distance up to 40 meters (1.65Gbps) and 35 meters (2.25Gbps). The MAX3815A is designed to equalize signals encoded in the transition-minimized differential signaling (TMDS®) format.

The MAX3815A 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.

The MAX3815A is available in a 7mm x 7mm, 48-pin TQFP-EP package and operates over a 0°C to +70°C temperature range.

Product Detail

The MAX3815A evaluation kit (EV kit) is an assembled demonstration board that allows in-system evaluation of the MAX3815A TMDS® cable equalizer and the MAX3816A DDC extender. The input and output connections are made through Molex HDMI™ connectors for direct connection to HDMI cables.

The DDC signals SDA and SCL are assisted by the MAX3816A. Hot-plug detect, +5V, DDC/CEC ground, and CEC simply pass through the board.

Power is delivered to the board through an external wall-plug transformer, which is included with this EV kit.

Applications

  • Front-Projector HDMI/DVI Inputs
  • HDMI 1.3 Deep Color Systems
  • HDMI/DVI-D Cable-Extender Modules and Active Cable Assemblies
  • High-Definition Televisions and Displays
