USB 3.2 Gen 1 Cable Extender Reference Design

The USB 3.2 Gen 1 Cable Extender reference design integrates a reclocked/driver IC right into a USB dongle, facilitating prolonged cable assist.

A USB 3.2 Gen 1 Cable Extender is an important software designed to increase the attain of USB connections with out sacrificing the sign integrity and high-speed efficiency inherent to USB 3.2 Gen 1 know-how. With the power to assist knowledge switch charges of as much as 5 Gbps and supply energy over prolonged distances, these extenders are important for settings the place units like cameras, printers, and storage models are removed from the central laptop or hub. They’re significantly helpful in environments akin to skilled audio-visual setups, digital signage, or massive workplace configurations, guaranteeing operational effectivity and adaptability in gadget placement. The USB 3.2 Gen, 1 Cable Extender reference design from Microchip options the EQCO5X31 IC built-in right into a compact USB dongle, which could be related at each the host and gadget ends. 

The reclocker/driver IC is designed for USB 3.2 Gen 1 networks to reinforce cable size and sign high quality, supporting longer cables. The gadget incorporates three key features. It contains an auto-adaptive equalizer on the receiver that mechanically compensates for frequency-dependent losses within the cable, a Reclocker that includes a bit-level Clock Information Restoration that re-times the sign to get rid of gathered jitter, and a Redriver that amplifies and transmits the cleaned-up sign onto a cable or PCB hint.

The end result is a tool that processes the sign on the Bodily layer by equalizing cable losses at its enter, reclocking, after which driving the sign out in each instructions. The efficiency relies on the standard of the cable and connectors; the reclocked/driver IC can assist as much as 16 meters of passive cable. Testing signifies that the EV40G35A card may also deal with between 8 to 10 meters of passive USB 3.2 Sort-C cable.

The design gives a number of advantages, making it superb for integration or modification into your present setup. It extends the lengths of USB 3.2 Gen 1 cables and enhances the efficiency of USB 3.2 Gen 1 (5Gbps) by equalizing, reclocking, and redriving the sign in each instructions. Moreover, it helps Sort-C reversibility and the complete VBUS voltage vary, offering versatile and strong connectivity options.

The board has two USB connectors: a Sort-C plug and a Sort-C receptacle. The plug connects on to a tool like a laptop computer, and the receptacle accepts a USB Sort-C cable. It options two EQCO5X31 elements that handle USB3 indicators by reclocking and driving them throughout two lanes in line with the USB Sort-C specification. Sometimes, just one lane is lively at a time, however the board may also assist each lanes being lively concurrently. 

Microchip has examined this reference design. It comes with a invoice of supplies (BOM), schematics, meeting drawing, printed circuit board (PCB) structure, and so forth.
