4 to 12-Output Buffers for PCIe Gen1–5 and UPI 9ZXL04x1E/9ZXL06x1E/ 9ZXL08x1E/9ZXL12x1E Datasheet Description The 9ZXL04x1E/9ZXL06x1E/9ZXL08x1E/9ZXL12x1E family of Zero-Delay/Fanout Buffers (ZDB, FOB) are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1–5 jitter specifications. Devices range from 4 to 12 outputs, with each output having an OE# pin to support the PCIe CLKREQ# function for low power states. All devices meet DB2000Q, DB1200ZL and DB800ZL jitter and skew requirements.
