Diodes Incorporated has introduced a series of USB ReDrivers for the industrial, embedded, and consumer market segments. The PI3EQX1004E and PI3EQX1002E are USB 3.2 compliant, 5Gbps to 10Gbps, 2-Port/1-Port, linear ReDrivers. The devices provide adjustable linear equalisation, output swing, and flat gain to optimise performance over a variety of physical media by reducing intersymbol interference.

They are the industry’s smallest ReDrivers and save board space by using packages that are up to 64% smaller than those traditionally used for similar products. Target applications include laptops, tablet PCs, desktop PCs, and gaming devices.

The ReDriver, also known as a repeater IC, regenerates signals to boost the signal quality of high-speed interfaces. Faster signal frequencies leave designers with less signal margin to design reliable, high-performance systems. Using equalisation, 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).

The PI3EQX1004E/1002E are built using Diodes’ patented technology, which enables them to extend PCB trace lengths while minimising 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 (4.5x2.5mm) package and is priced at $1.75 each in 1,000 piece quantities. The PI3EQX1002E is offered in a 24-contact UQFN (2.5x2.5mm) package and is priced at $1.20 each in 1,000 piece quantities.
