Low-Power CK420BQ Derivative for PCIe

Common Clock Architectures

932SQL450

General Description

The 932SQL450 is a low power version of the CK420BQ

synthesizer for Intel-based server platforms. It has 85-ohm

LP-HCSL outputs allowing for direct connection to 85-ohm

transmission lines. The 932SQL450 is driven with a 25MHz

crystal for maximum performance. It generates CPU outputs

of 100MHz. This device has a “low-drift” non-spread

SAS/SRC PLL for use in systems that need to communicate

across PCIe domains.

Recommended Application

Low Power CK420BQ w/Zout=85ohms or PCIe Common

Clocked Systems (CC)

Key Specifications

• CPU, SRC, NS_SRC and NS_SAS cycle-cycle jitter <50ps

• Output to output skew <50ps

• Phase jitter: PCIe Gen2 <2.5ps rms

• Phase jitter: PCIe Gen3 <0.6ps rms

• Phase jitter: QPI <0.3ps rms

• Phase jitter: NS-SAS <1.3ps rms using long period phase

jitter method

Features/Benefits

• Integrated 85 ohm differential terminations; saves 48

resistors and 82mm2 area

• LP-HCSL output drivers; 40% typical power savings over

932SQ420

• 0.5% down spread capable on CPU, SRC and PCI outputs;

reduce EMI

• Additional down spread amounts selectable via SMBus;

maximal system flexibility

• 64-pin TSSOP and VFQFPN packages; smallest board

footprint

Output Features

• 4 - Low-Power HCSL-compatible (LP-HCSL) CPU outputs

• 2 - LP-HCSL NS_SAS outputs

• 2 - LP-HCSL NS_SRC outputs

• 3 - LP-HCSL SRC outputs

• 1 - LP-HCSL DOT96 output

• 1 - 3.3V 48M output

• 5 - 3.3V PCI outputs

• 1 - 3.3V 14.318M output
