ReDriver supports PCIe 4.0; compatible with PCIe 3.0, 2.0, 1.0

A repeater IC or ReDriver for the server, storage, and networking markets from Diodes provides programmable linear equalisation, output swing, and flat gain to optimise performance over a variety of physical media by reducing inter-symbol interference.

The PI3EQX16904GL is a PCIe 4.0 compliant, 2.5Gbps to 16Gbps, four-differential channel, linear ReDriver. It is, says Diodes, the industry’s first ReDriver to support PCIe 4.0 while being backward-compatible with PCIe 3.0/2.0/1.0. Target applications for the device include storage and AI servers, workstations, 5G networking, CPU-to-network (PCIe NIC card) and CPU-to-storage (NVME) interconnects, and CPU-to-CPU interconnects within high-performance compute clusters.

The PI3EQX16904GL regenerates signals to boost the signal quality of high-speed interfaces. 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 for reliable communications with low bit error rates (BER).

The PI3EQX16904GL supports four 100Ω differential current mode logic (CML) data I/Os and extends the signals across other distant data pathways on the user’s platform. Linear ReDrivers are commonly used to achieve PCB trace extension while minimising cost and power consumption. They can also deliver lower latency.

The P13EQX16904GL operates over the industrial temperature range of -40 to +85 degrees C and requires a supply voltage of 3.3 ±0.3V.

It is offered in a 42-contact TQFN (9.0 x 3.5mm) package.

Diodes manufactures and supplies application specific standard products within the broad discrete, logic, analogue, and mixed-signal semiconductor markets. Diodes serves the consumer electronics, computing, communications, industrial, and automotive sectors, providing diodes, rectifiers, transistors, MOSFETs, protection devices, function-specific arrays, single gate logic, amplifiers and comparators, Hall-effect and temperature sensors, power management devices, including LED drivers, AC/DC converters and controllers, DC/DC switching and linear voltage regulators, and voltage references along with special function devices, such as USB power switches, load switches, voltage supervisors, and motor controllers. Diodes also has timing, connectivity, switching, and signal integrity solutions for high-speed signals.
