PCIe 4.0 ReDriver extends PCB trace lengths
A high-speed data rate ReDriver device has been announced by Diodes. The PI2EQX16924 is claimed to be the first PCIe 4.0 ReDriver that operates from a 1.8V voltage rail, rather than the conventional 3.3V rail. The ReDriver addresses a variety of computing and data communication applications, said Diodes.
The PI2EQX16924 only consumes 288mW in active and 27mW in low power modes, resulting in battery charge savings in portable applications.
There are four differential channels that are independently configurable in terms of receiver equalisation and flat gain. This mitigates inter-symbol interference and allows signal loss compensation, so that longer PCB trace lengths can be achieved. The I2C interface is used for this configuration, minimising firmware requirements.
The PI2EQX16924 is capable of handling data rates up to 16Gbits per second and operates in the industrial temperature range of -40 to +85 degrees C. It is compliant with PCIe 4.0 and backwards compatible with PCIe 1.0, 2.0 and 3.0 generations.
The PI2EQX16924 ReDriver is supplied in a 32-pin X2-QFN package.
