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.
