Renesas Introduces Industry’s First PCIe Gen6 Clock Buffers and Multiplexers
Renesas Electronics Corporation has launched the first clock buffers and multiplexers compliant with PCIe Gen6 specifications. The introduction includes 11 new clock buffers and 4 multiplexers, enhancing designs in data centers, networking, and industrial applications. Key features are ultra-low jitter of 4fs RMS, compact designs saving 30% space, and added reliability through selectable SMBus addresses. These devices pave the way for future-proof solutions in high-performance systems, reaffirming Renesas' positioning as a leader in timing solutions.
- Introduced first PCIe Gen6 compliant clock buffers and multiplexers.
- Ultra-low jitter performance (4fs RMS) enhances system reliability.
- 30% smaller size compared to previous models improves design efficiency.
- Supports both PCIe Gen5 and Gen6 for future scalability.
- None.

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.
“PCIe Gen6 timing will be at the heart of new equipment in data centers, high-speed networking and other applications,” said
“By delivering the first discrete timing solution for PCIe Gen6, Renesas is enabling customers to develop the next-generation of high-performance systems,” said
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
