Microchip EQCO510 / EQCO5X31 USB 3.2 Gen 1 Reclocker / Redriver

Automotive (EQCO510) or Industrial and commercial (EQCO5X31) Dual-Channel USB 3.2 Gen 1 Reclocker/Redriver

The EQCO5X31 is a fully qualified single chip USB 3.2 SuperSpeed Reclocker/Redriver with EyeOpen™ and MarginLink™ technology for the industrial and commercial market segments. The EQCO5X31 will reclock and drive a USB 3.2 SuperSpeed signal over a cable up to 16m reliably. Furthermore, the EQCO5X31 extends max cable length from a recommended 1m to 5m to meet the maximum length of USB2.0 and up to 16m for USB 3.2 links for longer reach applications. Now designers can easily create applications to support both USB 2.0 and USB 3.2 up to 5 meters and USB 3.2 only up to 16m meters in cable length.

The EQCO5X31 is a single chip (equalizer, driver, reclocker) that repeats high speed data signals with a rate of 5 Gbps. From a cable or PCB trace pair, the sig- nal 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 resets jitter back to meet USB 3.2 specifications 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 EQCO5X31 devices to the destination. The EQCO5X31 CDR restores signal integrity at each link along the way.

The EQCO510 is the automotive qualified version of EQCO5X31. The EQCO510 will reclock and drive a USB 3.2 SuperSpeed signal up to 15m reliably for the lifetime of a vehicle without changing the physical position of the breakout box using low cost cable.
