DATASHEET

19-OUTPUT DB1900Z LOW-POWER DERIVATIVE

9ZXL1930

Description

Features/Benefits

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.

• 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 incoming clock

• Selectable PLL BW; minimizes jitter peaking in

downstream PLL's

Recommended Application

Buffer for Romley, Grantley and Purley Servers

• Spread spectrum compatible; tracks spreading input

clock for EMI reduction

• SMBus Interface; unused outputs can be disabled

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

• 100MHz & 133.33MHz PLL mode; Legacy QPI/UPI

support

• Differential outputs are Low/Low in power down;

Maximum power savings

Output Features

• 19 - LP-HCSL Differential Output Pairs
