ReDrivers from Diodes Incorporated Boost Signal Quality of High-Speed USB 3.2, 10Gbps Interfaces

Diodes introduced a series of USB ReDrivers for application in industrial, embedded, and consumer electronics products. The PI3EQX1004E and PI3EQX1002E are USB 3.2 compliant, 5Gbps to 10Gbps, 2-Port/1-Port, linear ReDrivers. The devices are backwards compatible with USB 3.1 Gen 1, 5Gbps and offer ultra-small and thin package types to reduce PCB size and total BOM cost. They have adjustable linear equalization, output swing, and flat gain to optimize performance over a variety of physical media by reducing intersymbol interference. Both operate from a supply voltage of 3.3V.
 
The ReDriver, also known as a repeater IC, regenerates signals to boost the signal quality of high-speed interfaces. Since faster signal frequencies leave designers with less signal margin to design reliable, high-performance systems, using equalization, pre-emphasis, and other technologies, a single ReDriver can adjust and correct for known channel losses at the transmitter and restore signal integrity at the receiver. This enables reliable communications with low bit error rates (BER).

According to Diodes, the new USB ReDrivers are the industry’s smallest and save board space by using packages that are up to 64% smaller than those traditionally used for similar products. Typical target applications include laptops, tablet PCs, desktop PCs, and gaming devices. The PI3EQX1004E/1002E are built using Diodes’ patented technology, which enables them to extend PCB trace lengths while minimizing cost and power consumption. Linear ReDrivers can also deliver lower latency.
 
Requiring a supply voltage of 3.3V ±0.3V, PI3EQX1004E is offered in a 34-contact UQFN (4.5mm x 2.5mm), and the PI3EQX1002E is offered in a 24-contact UQFN (2.5mm x 2.5mm) package.
