DATASHEET

8-OUTPUT DB800ZL

9ZXL0831

General Description

Features/Benefits

The 9ZXL0831 is a low-power 8-output differential buffer

that meets all the performance requirements of the Intel

DB800ZL specification. 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.

• Low-power push-pull outputs; Save power and board

space - no Rp

• Space-saving 48-pin VFQFPN package

• Fixed feedback path for 0ps input-to-output delay

• 8 OE# pins; hardware control of each output

• PLL or bypass mode; PLL can dejitter incoming clock

• 100MHz or 133MHz PLL mode operation; supports PCIe

Recommended Application

Buffer for Romley, Grantley and Purley Servers, SSD drives

and PCIe

and QPI applications

• Selectable PLL bandwidth; minimizes jitter peaking in

downstream PLL's

Output Features

• 8 - LP-HCSL Output Pairs

• Spread Spectrum Compatible; tracks spreading input

clock for low EMI

Key Specifications

• Cycle-to-cycle jitter <50ps

• Output-to-output skew <65 ps

• Input-to-output delay variation <50ps

• PCIe Gen3 phase jitter <1.0ps RMS

• QPI/UPI 9.6GT/s 12UI phase jitter <0.2ps RMS
