Electronics Semiconductors clock buffers multiplexers PCIe

RENESAS ELECTRONICS RC190xx clock buffers (11) and RC192xx multiplexers (4) meet stringent PCIe Gen6 specifications. Devices also support and provide extra margin for PCIe Gen5 implementations, complement firm’s low-jitter 9SQ440, 9FGV1002 and 9FGV1006 clock generators to offer customers a complete PCIe Gen6 timing solution for data center/cloud computing, networking and high-speed industrial applications. The PCIe Gen6 standard supports high data rates of 64 GT/s while requiring low clock jitter performance of less than 100fs RMS. RC190xx and RC192xx both have PCIe Gen6 additive jitter specs of only 4fs RMS, making them virtually noiseless, and thereby future-proofing customer designs for the next generation of industry standards.

RC190xx buffers are offered in 4-, 8-, 13-, 16-, 20- and 24-output configurations. RC192xx multiplexers include 2-, 4-, 8- and 16-output versions. Devices are offered in packages as small as 3mm x 3mm. All of the new devices are available now, along with an evaluation board schematic.
