9ZXL1530BKLF

DATASHEET 9ZXL1530 15-OUTPUT DB1900Z LOW-POWER DERIVATIVE Description Features/Benefits The 9ZXL1530 is a 15-output version of the Intel DB1900Z Differential Buffer utilizing Low-Power HCSL (LP-HCSL) outputs to reduce power consumption more than 50% from the original IDT9ZX21501. 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. • Fixed feedback path; 0ps input-to-output delay • 9 Selectable SMBus addresses; Multiple devices can Recommended Application Buffer for Romley, Grantley and Purley Servers share same SMBus segment • Separate VDDIO for outputs; allows maximum power savings • PLL or bypass mode; PLL can dejitter incoming clock • Selectable PLL BW; minimizes jitter peaking in downstream PLL's • Spread spectrum compatible; tracks spreading input clock for EMI reduction • SMBus Interface; unused outputs can be disabled • 100MHz & 133.33MHz PLL mode; Legacy QPI/UPI Key Specifications • • • • • • Cycle-to-cycle jitter: < 50ps support Output-to-output skew:
