New PCIe Gen6 Clock Buffers and Multiplexers Offer High Output Count for Data Center/Cloud Computing and High-speed Industrial Applications

14 April 2022 - 0 Comments

Renesas Electronics Corporation has introduced 11 new clock buffers and 4 new multiplexers that support and provide an extra margin for PCIe Gen5 implementations, and complement Renesas’ 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 new RC190xx clock buffers and RC192xx multiplexers with numerous analog and power offer a winning combination that provides full power and timing for Intel’s latest-generation Xeon CPU platform.

The PCIe Gen6 standard supports extremely high data rates of 64 GT/s while requiring very low clock jitter performance of fewer than 100fs RMS. These new devices 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.

Features

Ultra-low 4fs PCIe Gen6 additive jitter, 1.4ns in-out delay, 35ps out-out skew, and -80dB Power Supply Rejection Ratio (PSRR) @100kHz easily ensure robust system design
30 percent space-saving compared to earlier devices
Selectable SMBus addresses allow easy use of multiple devices
SMBus write-protect feature enhances system security
Loss-Of-Signal (LOS) output supports system monitoring and redundancy
4-wire Side-Band interface supports high-speed serial output enable/disable and device daisy-chaining
Power Down Tolerant (PDT) and Flexible Start-up Sequencing (FSS) features ensure good behavior under abnormal system conditions

Applications

Data center/cloud computing
Networking
High-speed industrial applications

Availability

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