DATASHEET
Description
The 9ZXL1550 is a DB1900Z derivative buffer utilizing Low-Power HCSL (LP-HCSL) outputs to increase edge rates on long traces, reduce board space, and reduce power consumption more than 50% from the original 9ZX21501. It is pin-compatible to the 9ZXL1530 and has the output terminations integrated. It is suitable for PCI-Express Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift for demanding QPI/UPI applications.
Recommended Application
Buffer for Romley, Grantley and Purley Servers
