EQCO3400

The EQCO3400 True Colour HDMI cable equalizer provides fully adaptive compensation for signal attenuation over DVI, HDMI, DFP, DisplayPort, PanelLink®, and ADC cables at signal speeds up to 3.4 Gbps. With industry standard cables, it extends the usable range to up to 25 meters.

The EQCO03400 features four differential inputs and outputs (three data and one clock) and four independent equalisers. It also provides a signal present indication for use with external wakeup circuits. The device is designed to equalize signals encoded in the transition-minimized differential signalling (TMDS) format. It is designed to be a plug in replacement to the Maxim 3815 with enhanced bandwidth performance.
