Introducing IDT’s 9Z, enhanced PCIe clock buffer family. The PCIe gen 4 clock buffers offer fanout, 1 MHz and 3 MHz bandwidth zero-delay operating modes, providing flexibility to support the most complex timing trees with a single device. Unlike many existing solutions, whose performance limitations force their use in fanout buffer mode, the 9Z family supports prominent CPU phase jitter requirements in all three operating modes. The extremely low 50 fs rms PCIe Gen4 additive phase jitter enables complex implementations requiring cascading, while still meeting PCIe Gen4 requirements. These PCI Express clock fanout buffers are also ideal for interfacing with IDT’s high-performance oscillators when board designs require a wide clock distribution from a single source.
