932SQL450BKLF

Low-Power CK420BQ Derivative for PCIe Common Clock Architectures 932SQL450 DATASHEET General Description Features/Benefits 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. • 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 Recommended Application • Low Power CK420BQ w/Zout=85ohms or PCIe Common Clocked Systems (CC) Output Features Key Specifications • • • • • • CPU, SRC, NS_SRC and NS_SAS cycle-cycle jitter
