General Description
The EQCO125X40 is a single chip (equalizer, driver, reclocker) that repeats high-speed 8b/10b coded data signals with a downstream bit-rate between 1.25 to 12.5 Gbps. From a cable or PCB trace pair, the signal

is received by an auto-adaptive equalizer that compensates for higher-frequency losses in the preceding channel. A reference-less Clock-Data Recovery (CDR) subsequently self-adapts to the incoming bit-rate and resets the jitter back to a low value for maintaining signal integrity. A cable driver launches this clean signal back onto a cable or PCB trace pair. When placed in series as a repeater, a signal can travel through several EQCO125X40 Family devices to the destination. The EQCO125X40 CDR restores signal integrity at each link along the way.
The high-speed direction (or downlink) has a simultaneous complementary uplink, operating at 20.833 Mbps or 41.666 Mbps 8b/10b coded signaling. This uplink also includes an equalizer, a reference-less CDR and a cable driver, operating with a transparent full-duplex and self-adaptive downlink.
The EQCO125X40 Family can be used as a CoaXPress transmitter inside a camera, as a CoaXPress receiver inside a frame grabber and as a CoaXPress repeater inside an active coax cable or link. It can also be used as a generic high-speed signaling transport for any 8b/10b application. In general it can be regarded as an ideal means for using the high bit-rate ports on an FPGA in real-world applications. This allows the highspeed signal to get an increase in signal integrity along its signaling path at strategic places: e.g. when changing the signaling nature from single-ended to differential or vice-versa, after long runs of cable, or recovering the signal from skin effect and/or dielectric losses. The CDR resets accumulated jitter due to small impedance mismatches, non-ideal connectors, PCB-vias, etc., and yields better signal integrity. This is also useful when the signal chain includes an optical link.

1.0 BASIC APPLICATION INFORMATION
The EQCO125X40 repeater chip is designed to simultaneously transmit and receive 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, reclocker and cable driver. The uplink channel also has an integrated receiver, reclocker and driver. Figure 1-1 illustrates a typical EQCO125X40 link set-up.
The downlink signal is transmitted with 600 mV transmit amplitude. As this signal is attenuated by the coax (or STP) over distance, it is recovered by the equalizer and reclocker. The low-speed uplink is transmitted with a lower amplitude of 130 mV to limit the crosstalk with the downlink channel.
The downlink channel is intended for NRZ 8b/10b data with bit-rates between 1.25 Gbps and 12.5 Gbps. CoaXPress standard speeds of CXP-1 (1.25 Gbps), CXP-2 (2.5 Gbps), CXP-3 (3.125 Gbps), CXP-5 (5 Gbps), CXP-6 (6.25 Gbps), CXP-10 (10 Gbps) and CXP-12 (12.5 Gbps) are all supported as well as all generic 8b/10b applications.
The low-speed uplink is intended for NRZ 8b/10b data with bit-rates between 20 Mbps and 42 Mbps with a single-ended 1.25V LVTTL input and output. CoaXPress standard speeds of 20.833 Mbps and 41.666 Mbps are supported.
On top of the downlink channel and the low-speed uplink, the system allows power transmission over the coax by using external inductors. These external inductors give the communication channel a high-pass characteristic. The uplink receiver inside the EQCO125X40 chip recovers the signal lost by this high-pass filter. Appropriate inductors should be selected for correct operation of the link. Operation has only been tested with the inductor combination used in Microchip's reference design, even though other components might be suitable.
