Low-Power CK420BQ Derivative for PCIe 932S Q L 456 Separate Clock Architectures D A T A S H E E T General Description Features/Benefits The 932SQL456 is a low power version of the CK420BQ Integrated 85-ohm differential terminations saves 48 synthesizer for Intel-based server platforms. It has 85 ohm resistors compared to CK420BQ Low-Power (LP) HCSL outputs that save 48 resistors and LP-HCSL outputs up to 50% power savings compared to reduce power consumption by 50% compared to the standard standard CK420BQ CK420BQ. The 932SQL456 is driven with a 25MHz crystal for 64-pin TSSOP and VFQFPN packages smallest board maximum performance. It generates CPU outputs of footprint 100MHz. This device meets Separate- Reference-no-Spread Available in -40 to +85C industrial temperature range (SRnS) PCIe requirements making it ideal for use in systems version supports demanding operating environments that need to communicate outside the box.
