Procurement Notes

Verify the ordering suffix 'T3' corresponds to Tape & Reel packaging containing 3,000 pieces per reel. Confirm the 'L' suffix indicates the extended operating temperature range of -40°C to +85°C. Ensure the 'HC' and 'LP' codes match the required HCSL and LVPECL output formats respectively. Cross-reference the part number against the manufacturer's latest documentation to confirm current production status and compliance with RoHS/RoHS II standards.

Selection Notes

Select this component when a compact, crystal-less clock generator is required for PCIe or high-speed serial interfaces. The AB-557-03 series is suitable for designs needing mixed output formats like HCSL and LVPECL. Consider the 14-QFN package dimensions (3.2x2.5x0.85mm) for space-constrained PCB layouts. Verify that the input frequency requirements align with the device's capabilities, noting that non-100MHz frequencies may require specific configuration or alternative series consultation.

Part Context

This part belongs to the AB-557-03 series of Pure Silicon™ clock generators. These devices are designed as direct replacements for traditional crystal oscillator solutions, offering reduced board space and improved reliability due to solid-state construction. The series supports various output formats and temperature ranges to accommodate diverse industrial and commercial electronic applications.

Replacement Considerations

For equivalent functionality, consider other Abracon Pure Silicon™ series parts or Discera MEMS oscillators. Verify pin compatibility and electrical parameters such as jitter specs and supply voltage before substitution. Check if alternative packages are available if footprint constraints differ.
