The EQCO125X40 CoaXPress 2.0 transmitter/receiver/repeater chip is designed to simultaneously transmit signals on a single cable or PCB trace pair. In one direction an 8b/10b coded downlink signal is transmitted between 1.25 Gbps and 12.5 Gbps. In the opposite direction a lower speed 8b/10b coded uplink signal is transmitted at 20.833 Mbps or 41.666 Mbps. The EQCO125X40 has an integrated high speed equalizer, re-clocker and cable driver. The uplink channel also has an integrated receiver, re-clocker and driver. The downlink signal is transmitted with 600 mV transmit amplitude.
