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

Overview

The AB-557-03-HCLV-S-L-C-T3 is a crystal-less PCI Express dual output ultra miniature Pure Silicon SMD clock generator from Abracon LLC. It operates within a supply voltage range of 2.25 V to 3.6 V and supports frequencies up to 460 MHz. The device features two differential outputs with mixed formats: HCSL for CLK0 and LVDS for CLK1. Packaged in a 14-pin QFN (3.2 x 2.5 x 0.85 mm), it provides low jitter performance suitable for high-speed interfaces, including PCIe Gen 1.1, Gen 2.1, and Gen 3.0 specifications.

Feature Summary

• Crystal-less design utilizing Pure Silicon MEMS technology
• Dual differential outputs: HCSL (CLK0) and LVDS (CLK1)
• Low jitter performance meeting PCIe Gen 1.1 through Gen 3.0 standards
• 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 package type against the model suffix. The datasheet identifies the AB-557-03 series as a 14-pin QFN component. Confirm that the requested 16-TSSOP package designation does not conflict with the official documentation before procurement.

Selection Notes

Select this component for designs requiring mixed output signaling levels without an external crystal. Ensure the load requirements match the specified HCSL and LVDS configurations. Verify frequency stability needs against the ±100 ppm option provided by the 'Blank' suffix in the part number structure.

Part Context

This part belongs to the AB-557-03 series, which utilizes Discera's Pure Silicon MEMS technology. The series is designed as a drop-in replacement for traditional crystal oscillators, offering solid-state storage and immunity to shock and vibration while maintaining compliance with RoHS/RoHS II directives.

Replacement Considerations

For frequencies other than 100 MHz, the ASEMDxx series is recommended. Cross-reference pinouts carefully if replacing legacy crystal oscillator solutions, as this is a crystal-less PLL-based generator.
