The 9ZXL0851E is a second-generation enhanced performance DB800ZL differential buffer. The part is a pin-compatible upgrade to the 9ZXL0851A while offering a much-improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
The evaluation board is designed to help the customer evaluate the 9ZXL1951D. The device is programmable through an SMBus interface. The user guide details the board...

Introducing Renesas’ enhanced PCIe clock buffer family. These PCIe Gen5 clock buffers offer fanout and zero-delay operating modes, supporting both legacy systems and the most complex timing trees within a single device. Unlike many existing solutions, whose performance limitations force their use in fanout buffer mode, these clock buffers meet both PCIe Gen5 and prominent CPU-specific phase jitter requirements in all operating modes. The extremely low 50fs rms PCIe Gen5 additive phase jitter enables multi-level cascading within the strict PCIe Gen5 jitter budget. Renesas’ high-performance oscillators and clock generators provide an ideal clock source for the enhanced PCIe clock buffer family.
