Overview

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".

  • Integrated 85Ω differential terminations; saves 48 resistors compared to CK420BQ
  • LP-HCSL outputs; up to 50% typical power savings compared to standard CK420BQ
  • 64-pin TSSOP and VFQFPN packages; smallest board footprint
  • CPU, SRC, NS_SRC and NS_SAS cycle-cycle jitter < 50ps
  • Output to output skew < 50ps
  • Phase jitter: PCIe Gen 2 < 2.2ps rms
  • Phase jitter: PCIe Gen 3 < 0.7ps rms
  • Phase jitter: QPI < 0.3ps rms
  • Phase jitter: NS-SAS < 1.3ps rms using long period phase jitter method
  • Available in -40 °C to +85 °C industrial temperature range version; supports demanding operating environments

Applications

  • Low-power CK420BQ for SRnS PCIe applications
