PCI EXPRESS 5.0 transceiver and reference clock solution Tektronix, in collaboration with Anritsu, has introduced a PCI EXPRESS 5.0 transceiver (Base and CEM) and reference clock solution. It is the first company to offer early CEM fixtures for pre-compliance testing. The collaboration between Tektronix and Anritsu enables receiver verification, complementing a leading transmitter and reference clock test suite. PCI EXPRESS is viewed as the dominant high-speed serial computer bus and has been doubling bandwidth every three years and is exceeding that target with this aggressive introduction of the 5.0 Base Specification (128 GB/s). This rapid pace of development is expected to continue as PCI-SIG, the standard-setting body for peripheral component I/O data transfers, has announced the PCI EXPRESS 6.0 specification (256 GB/s) which is to be delivered in 2021 and includes multi-level PAM4 signaling.
