AB-557-03-HCC-S-L-C-T3

Overview

The AB-557-03-HCC-S-L-C-T3 is a crystal-less PCI Express dual output ultra-miniature Pure Silicon SMD clock generator manufactured by Abracon LLC. It operates within a supply voltage range of 2.25V to 3.6V and supports frequencies up to 460MHz. The device features HCSL and LVCMOS outputs, with an operating temperature range of -40°C to +85°C. It utilizes MEMS technology for high shock and vibration immunity. The component is housed in a 16-TSSOP package (0.173" width) and is designed for PCIe Gen 1, 2, and 3 specifications.

Feature Summary

• Crystal-less design using Pure Silicon MEMS technology
• Dual output formats: HCSL and LVCMOS
• Frequency range from 2.3 MHz to 460 MHz
• Operating temperature range of -40°C to +85°C

Applications

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

Procurement Notes

Verify the package type against official documentation, as local descriptions indicate 16-TSSOP while standard datasheets specify 14-QFN. Confirm the suffix 'T3' corresponds to tape and reel packaging containing 3,000 pieces per reel. Ensure the ordering code matches the required frequency stability and output format options defined by the manufacturer.

Selection Notes

Select this component for designs requiring low power consumption and solid-state storage reliability. The wide supply voltage range of 2.25V to 3.6V accommodates various logic levels. Verify that the 16-TSSOP footprint aligns with the PCB layout, as the series typically uses a 14-pin QFN package. Check if the specific frequency requirement falls within the supported range or requires contacting the manufacturer.

Part Context

This part belongs to the AB-557-03 series of crystal-less clock generators. The series is characterized by its ultra-miniature form factor and compliance with RoHS/RoHS II standards. It is classified under Application Specific Clock/Timing products and is suitable for commercial and industrial environments.

Replacement Considerations

For alternative packages, consider the 14-QFN variant (suffix 'F') of the same series. If different output formats are needed, explore options with LVPECL or LVDS configurations. Verify pin compatibility and thermal requirements when substituting.
