Overview
EVB-EQCO5X31 USB 3.2 GEN 1 Cable Repeater
The EV23B43A is a card that incorporates the EQCO5X31 IC onto a small USB dongle that can be used to connect and repeat two cable segments. The EQCO5X31 IC is a device that can be used on USB 3.2 Gen 1 networks to extend cable distances and improve signal quality to allow for longer cables to be supported. Microchip has called the EQCO5X31 IC a USB Reclocker/Redriver. It includes three functions:
1. An auto-adaptive equalizer at the receiver which automatically adjusts for frequency dependent losses in the cable
2. A Reclocker which includes a bit-level CDR that re-times the signal to reset accumulated jitter
3. A Redriver that drives the cleaned-up signal onto a cable or PCB trace
The result is a device that simply passes through the signal at the Physical layer, equalizing the cable losses at its input, reclocking and redriving the signal back out, for both directions. Depending on the cable and connector quality, the EQCO5X31 can support up to 16m of passive cable. Testing has shown that the EV23B43A card can connect and repeat two 6-8m passive USB 3.2 Type-C cable segments. Multiple repeaters can be used to extend to even longer lengths.
