Eight-channel ReDriver has PCIe 4.0 interfaces

Extending its linear ReDriver ICs, Diodes has added the PI3UPI1608 with internal coupling capacitors. The IC can “significantly” extend PCB trace lengths while minimising power consumption and associated bill of materials costs, says the company.

It supports speeds of up to 20Gbits per second and is UPI 2.0 and PCIe 4.0- compliant with eight differential channels. Integral coupling capacitors save board area by reducing the number of external components required. can be avoided.

Key applications include AI servers, data storage equipment, 5G networking infrastructure and high-performance PCs as well as CPU-to-CPU and CPU-to-storage interconnects.

The PI3UPI1608 ReDriver compensates for channel losses at the transmitter and improves signal integrity at the receiver. It is also optimised for high-performance systems operating at elevated frequencies.

The programmable linear equalisation, output swing, and flat gain capabilities enable the PI3UPI1608 to reduce bit error rates (BERs) and lower intersymbol interference. Programmability can be carried out via the pin strap and I2C interface.

The PI3UPI1608 ReDriver IC runs off a 3.3V supply and has an operating temperature range of -40 to +85 degrees C. It is supplied in a 116-pin QFN package which measures 13 x 7.0mm.

Diodes delivers semiconductor products to companies in the consumer electronics, computing, communications, industrial, and automotive markets. Its product portfolio includes discrete, analogue and mixed-signal products and packaging technology to meet customers’ needs. There are 31 sites around the world, including engineering, testing, manufacturing, and customer service.
