DATASHEET

PCIE GEN 2/3 & QPI CLOCK FOR ROMLEY-BASED SERVERS

932SQ428

General Description

Features/Benefits

The 932SQ428 is a main clock synthesizer for

• 0.5% down spread capable on SRC/PCI outputs; Lower

Romley-generation Intel based server platforms. The

932SQ428 is driven with a 25 MHz crystal for maximum

performance. It generates CPU outputs of 100MHz.

EMI

• 48-pin MLF package; Space Savings

Key Specifications

• Cycle to cycle jitter: SRC/NS_SAS < 50ps

• Phase jitter: PCIe Gen2 <3ps rms

Recommended Application

CK420BQ

• Phase jitter: PCIe Gen3 <1ps rms

Output Features

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

• Phase jitter: NS-SAS <0.4ps rms using raw phase data

• Phase jitter: NS-SAS <1.3ps rms using Clk Jit Tool 1.6.3

• 2 - HCSL Non-Spread SAS outputs

• 3 - HCSL SRC outputs - can be used as CPU@100M

• 1 - HCSL DOT96 output

• 1 - 3.3V 48M output

• 5 - 3.3V PCI outputs

• 1 - 3.3V 14.318M output
