CK420BQ DERIVATIVE SUPPORTING SRNS PCIE CLOCKING
932SQ426
General Description
Features/Benefits
The 932SQ426 is a CK420BQ derivative supporting Separate Reference no Spread (SRnS) PCIe clocking architectures. It uses a 25MHz crystal for maximum performance and has 100MHz outputs tuned for non-spreading applications to provide the most open eye diagram on PCIe links.
• Non-spread 100MHz outputs/ Supports SRnS PCIe
architectures
• 64-pin TSSOP and VFQFPN packages; maximum space
savings
