9ZXL1950

19-output DB1900Z Low-Power Derivative w/85ohm Terminations 9ZXL1950 DATASHEET General Description The 9ZXL1950 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 9ZX21901.It is pin-compatible to the 9ZXL1930 and fully integrates the output terminations. 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 Output Features 19 LP-HCSL output pairs w/integrated terminations (Zo = 85 Key Specifications Cycle-to-cycle jitter: <50ps Output-to-output skew: <50ps Input-to-output delay variation: <50ps Phase jitter: PCIe Gen3 <1ps rms Phase jitter: QPI/UPI 9.6GB/s <0.2ps rms Features/Benefits LP-HCSL outputs; up to 90% IO power reduction, better si...
