Overview
Description
The 932SQL456 is a low-power version of the CK420BQ synthesizer for Intel-based server platforms. It has 85Ω low-power (LP) HCSL outputs that save 48 resistors and reduce power consumption by 50% compared to the standard CK420BQ. The 932SQL456 is driven with a 25MHz crystal for maximum performance. It generates CPU outputs of 100MHz. This device meets Separate-Reference-no-Spread (SRnS) PCIe requirements making it ideal for use in systems that need to communicate "outside the box".
