15-Output Differential Zbuffer for PCIe Gen2/3 and QPI

Description

Features/Benefits

The ICS9ZX21501 is a 15 output version of the Intel DB1900Z

Differential Buffer suitable for PCIe Gen3 or QPI applications. The

part is backwards compatible to PCIe Gen1 and Gen2. An adjustable

external feedback path allows the user to eliminate trace delays

from their design while maintaining low drift for critical QPI

applications. In bypass mode, the ICS9ZX21501 can provide

outputs up to 400MHz.

•

External feedback path/ Adjustable input-to-output delay

9 Selectable SMBus addresses/ Multiple devices can

share same SMBus segment

•

7 dedicated OE# pins/ hardware control of outputs

PLL or bypass mode/ PLL can dejitter incoming clock

Selectable PLL BW/ minimizes jitter peaking in

downstream PLL's

Recommended Application

15 output PCIe Gen3/QPI buffer with adjustable feedback for

Romley platforms

•

Spread spectrum compatible/tracks spreading input clock

for EMI reduction

•

SMBus Interface/ unused outputs can be disabled

100MHz & 133.33MHz PLL mode/ Legacy QPI support

Undriven differential outputs in Power Down mode for

maximum power savings

Output Features

•

15 - 0.7V current mode differential HSCL output pairs

Key Specifications

•

Cycle-to-cycle jitter: < 50ps

Output-to-output skew: <65ps

Input-to-output delay: User adjustable

Input-to-output delay variation: <50ps

Phase jitter: PCIe Gen3 < 1ps rms

Phase jitter: QPI 9.6GB/s < 0.2ps rms
