9ZXL0852E

9ZXL06x2E/9ZXL08xxE/9ZXL12x2E 6 to 12-Output Buffers for PCIe Gen1–5 and UPI with SMBus Write Protect Datasheet The 9ZXL revision E family of Zero-Delay/Fanout Buffers (ZDB, FOB) with SMBus Write Protect are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The devices have hardware SMBUS write protection to prevent accidental writes. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1–5 jitter specifications. Devices range from 6 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.
