9ZXL1252E Overview
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.
