9ZXL1930

19-OUTPUT DB1900Z LOW-POWER DERIVATIVE DATASHEET 9ZXL1930 Description The 9ZXL1930 is a low power version of the Intel DB1900Z Differential Buffer utilizing Low-Power HCSL (LP-HCSL) outputs to reduce power consumption more than 50% from the original IDT9ZX21901. 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: <85ps Input-to-output delay: Fixed at 0 ps Input-to-output delay variation: <50ps Phase jitter: PCIe Gen3 < 1ps rms Phase jitter: QPI/UPI 9.6GB/s < 0.2ps rms Features/Benefits Fixed feedback path; 0ps input-to-output delay 9 Selectable SMBus addresses; Multiple devices can share same SMBus segment Separate VDDIO for outputs; allows maximum power savings PLL or bypass mode; PLL can dejitter ...
