PCI Express 5.0 supporting interface chips from Diodes

Interface and discrete semiconductor maker Diodes has launched a range of semiconductor chips targeting PC interface standard PCI Express 5.0 protocol. The new PCI Express 5.0 interface allows for 32Gb/s of data transfer in a single channel, which doubled the throughput of PCI Express 4.0. A x 16 PCIe Gen 5 connection has a total bandwidth around 128 GB/s. The higher throughput of the data transfer requires even lower jitter clock signal than PCI Express 4.0. Semiconductor devices announced by Diodes include ReDriver, switch, clock generator, and clock buffer devices. ReDriver PI3EQX32908 supports 32Gbps data rates defined by PCIe 5.0 specification with eight differential channels, with independent channel configuration. Linear equalization, output swing, and flat gain parameters are all programmable, so that the signal loss issues can be minimized and PCB trace lengths extended. In line with Modern Standby requirements, this device draws less than 5mW of power when the system in which it is incorporated is in deep standby mode. As well as PCIe 5.0 architecture, the ReDriver also supports SAS4 and CXL protocols. DIODES PI2DBS32212 is claimed as the industry’s first PCIe 5.0 switches. Offering bidirectional operation PI2DBS32212 features 2:1 passive Mux and DeMux functionality. With specifications such as Bit-to-bit skew of 3ps (typical), channel-to-channel skew of only...
