ReDriver extends PCB trace lengths while minimising power consumption

Diodes Incorporated strengthens its range of PCIe solutions with the new high-speed data rate ReDriver device. The DIODES PI2EQX16924 is the industry’s first available PCIe 4.0 ReDriver that functions from a 1.8V voltage rail, whereas competing solutions must employ a 3.3V rail. It handles a wide variety of computing and data communication applications.

The device only consumes 288mW and 27mW, respectively, when in active and low-power modes, which is particularly important for saving battery charge in portable applications.

The device provides four differential channels that are independently configurable in terms of receiver equalisation and flat gain. This mitigates inter-symbol interference and enables signal loss compensation so that longer PCB trace lengths can be achieved. As the I2C interface is employed for such configuration work, firmware necessities are minimal.

The device can handle data rates up to 16Gbps. It is compliant with PCIe 4.0 and backwards compatible with PCIe 1.0, 2.0 and 3.0 generations. An industrial temperature range from -40C to 85C is supported.
