ICS9DB423B

REV E 091812

General Description

The ICS9DB423B is compatible with the Intel DB400Q

Differential Buffer Specification. This buffer provides 4

PCI-Express SRC or 4 QPI clocks. The ICS9DB423B is

driven by a differential output pair from a CK410B+ or

CK509B main clock generator.

Recommended Application

DB400Q compatible part with PCIe Gen1, Gen 2 and QPI

support

Key Specifications

• Output cycle-cycle jitter < 50ps

• Output to Output skew <50ps

• Phase jitter: PCIe Gen1 < 86ps peak to peak

• Phase jitter: PCIe Gen2 < 3.0/3.1ps rms

• Phase jitter: QPI < 0.5ps rms

Features/Benefits

• Spread spectrum modulation tolerant, 0 to -0.5% down

spread and +/- 0.25% center spread

• Supports undriven differential outputs in Power Down

and DIF_STOP# for modes for power management.

Output Features

• 4 - 0.7V current-mode differential output pairs

• Supports zero delay buffer mode and fanout mode

• Bandwidth programming available

• 50-133 MHz operation in PLL mode

• 33-400 MHz operation in Bypass mode
