General Description

The 9ZXL1230 is a small-footprint, low power 12-output

differential buffer that meets all the performance

requirements of the Intel DB1900Z specification. It is pin

compatible to the 9ZX21200. The 9ZXL1230 is backwards

compatible to PCIe Gen2 and QPI 6.4GT/s specifications. A

fixed, internal feedback path maintains low drift for critical

QPI applications.

Recommended Application

12-output Low Power PCIe Gen3/QPI differential buffer for

Romley

Output Features

• 12 - 0.7V low-power HCSL-compatible output pairs

Features/Benefits

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

space - no Rp

• Pin compatible to 9ZX21200; easy path to >50 power

savings

• Space-saving 56-pin QFN package

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

• 9 Selectable SMBus Addresses; Mulitple devices can

share the same SMBus Segment

• 4 OE# pins; Hardware control of four outputs, other

outputs free run

• PLL or bypass mode; PLL can dejitter incoming clock

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

and QPI applications

• Selectable PLL bandwidth; minimizes jitter peaking in

downstream PLL's

• 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 9.6GT/s 12UI phase jitter
