• Dual output formats: HCSL and LVPECL
• Meets PCIe Gen1, Gen2, & Gen3 jitter specifications
• Wide operating temperature range: -40°C to +85°C

Applications

• PCI Express (PCIe) systems
• Storage Area Networks (SAN)
• Passive Optical Networks (PON)
• Ethernet applications (1G, 10GBASE-T/KR/LR/SR, FCoE)

Procurement Notes

Verify the specific ordering suffixes against official documentation to ensure correct output format, stability, and packaging quantity. Confirm that the selected variant matches the required frequency and temperature range for the target application environment.

Selection Notes

Select this component when a compact, crystal-less clock solution is needed for high-speed serial interfaces like PCIe. Ensure the system design accommodates the 2.25V to 3.6V supply voltage and utilizes the appropriate termination resistors for HCSL and LVPECL outputs as specified in the datasheet.

Part Context

This part belongs to the AB-557-03 series, which includes variants in different packages such as 14-QFN. The 'HCLP' suffix indicates mixed output formats of HCSL and LVPECL, while 'T3' denotes tape and reel packaging containing 3,000 pieces per reel.

Replacement Considerations

Direct replacements must match the 16-TSSOP package and support both HCSL and LVPECL outputs. Verify compatibility with PCIe Gen1/2/3 jitter requirements and ensure the replacement device operates within the same 2.25V to 3.6V supply range.
