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

Overview

The AB-557-03-HCC-F-L-C-T3 is a crystal-less dual-output clock generator from the Pure Silicon™ series by Abracon LLC. It operates within a frequency range of 2.3 MHz to 460 MHz and supports a supply voltage of 2.25 V to 3.6 V. The device features HCSL output formats for both channels, housed in a 14-QFN (3.2x2.5 mm) package with an exposed pad. Designed for high-performance timing applications, it meets PCIe Gen 1.1 through Gen 3.0 specifications with integrated phase noise as low as 0.165 ps RMS. The unit includes enable/disable functionality and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Crystal-less design utilizing MEMS technology for shock and vibration immunity
• Dual outputs with mixed format options including HCSL, LVCMOS, LVPECL, and LVDS
• Compliance with PCIe Gen 1.1, Gen 2.1, and Gen 3.0 jitter specifications
• Low power consumption with 60 mA typical supply current at enabled state

Applications

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

Procurement Notes

Verify the T3 suffix indicates a tape and reel quantity of 3,000 pieces per reel. Confirm that the L suffix corresponds to the -40°C to +85°C operating temperature range. Ensure the HC designation matches the required HCSL output format for both CLK0 and CLK1 channels before finalizing procurement orders.

Selection Notes

Select this component when a compact, crystal-less solution is required for PCIe or high-speed serial links. The HCSL output format is suitable for specific driver requirements; verify compatibility against LVCMOS or differential alternatives if signal integrity constraints differ. Ensure the 2.25V to 3.6V supply range aligns with the system's power architecture.

Part Context

This part belongs to the AB-557-03 series of ultra-miniature SMD clock generators. The series offers various output combinations and packaging options. The specific model utilizes the 14-pin QFN form factor, distinguishing it from larger packages or single-output variants within the broader product family.

Replacement Considerations

For alternative frequencies outside the standard 100 MHz configuration, consult the ASEMDxx series. Cross-model substitution requires verification of output voltage levels, pinout compatibility, and thermal performance characteristics.
