Not recommended for new designs, please use the EQCO31X20, EQCO62X20, EQCO125X40 or EQCO125T40 for new designs. For speeds from 1.25 Gbps to 3.125 Gbps, we recommend all new designs begin with our latest CoaXPress Device EQCO31X20. The EQCO31R20 auto adaptive coaxial cable video equalizer is designed for asymmetric bi-directional communication over 75-ohm and 50-ohm coaxial cable. It supports 8b/10 NRZ coding and the CoaXPress® Standard. The EQCO31R20 enables simultaneous downlink, uplink and power over a single coaxial cable .
