Industry's First PCIe Gen6 Clock Buffers and Multiplexers

­Renesas Electronics Corporation introduced the first clock buffers and multiplexers that meet stringent PCIe Gen6 specifications. Renesas, the industry’s undisputed leader in timing solutions, is offering 11 new clock buffers and 4 new multiplexers. The new devices, which also support and provide extra margin for PCIe Gen5 implementations, 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 PCIe Gen6 standard supports extremely high data rates of 64 GT/s while requiring very low clock jitter performance of less than 100fs RMS. Renesas’ new RC190xx clock buffers and RC192xx multiplexers 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.

Key Features of Renesas’ PCIe Gen6 Clock Buffers and Multiplexers

• 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
