9ZXL1550

15-output DB1900Z Low-Power Derivative 9ZXL1550 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 Key Specifications Cycle-to-cycle jitter: < 50ps Output-to-output skew: <75ps Input-to-output delay variation: <50ps Phase jitter: PCIe Gen3 < 1ps rms Phase jitter: QPI 9.6GB/s < 0.2ps rms Block Diagram Features/Benefits LP-HCSL outputs; up to 90% IO power reduction, better signal integrity over long traces Direct connect to 85Ω transmission lines; eliminates 60 term...
