1 / 24 page  DATASHEET 932SQL456 REVISION B 09/29/15 1 Low-Power CK420BQ Derivative for PCIe Separate Clock Architectures 932SQL456 General Description The 932SQL456 is a low power version of the CK420BQ synthesizer for Intel-based server platforms. It has 85 ohm 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. Recommended Application Low-Power CK420BQ for SRnS PCIe Applications Key Specifications • CPU, SRC, NS_SRC and NS_SAS cycle-cycle jitter <50ps • Output to output skew <50ps • Phase jitter: PCIe Gen2 SRnS <2.2ps rms • Phase jitter: PCIe Gen3 SRnS <0.7ps 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 compared to CK420BQ • LP-HCSL outputs; up to 50% power savings compared to standard CK420BQ • 64-pin TSSOP and VFQFPN packages; smallest board footprint • Available in -40° to +85°C industrial temperature range version; supports demanding operating environments Output Features • Differential outputs are LP-HCSL with integrated 85 terminations • 11 non-spreading interchangeable 100MHz differential outputs • 4 CPU outputs • 2 NS_SAS outputs • 2 NS_SRC outputs • 3 SRC outputs • 1 DOT96 96MHz output • 1 3.3V 48M output • 5 3.3V PCI outputs • 1 3.3V 14.318M output Pin Configurations Note: Pins with ^ prefix have internal 120K pullup Pins with v prefix have internal 120K pulldown GNDPCI VDDPCI PCI4_2x PCI3_2x PCI2_2x PCI1_2x PCI0_2x GNDPCI VDDPCI VDD48 48M_2x GND48 GND96 DOT96_Z85T DOT96_Z85C AVDD96 Note: Pins with ^ prefix have internal 120K pullup Pins with v prefix have internal 120K pulldown |
