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

Overview

The AB-557-03-HCC-F-L-C-T is a crystal-less dual-output clock generator from the Pure Silicon™ series 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 output format for both channels, housed in a compact 14-QFN (3.2x2.5mm) package. Key electrical parameters include a typical supply current of 60mA, a startup time of 5ms, and an overall frequency stability of ±100ppm. It meets PCIe Gen1, Gen2, and Gen3 specifications with integrated phase noise performance.

• Passive Optical Networks (PON)
• Ethernet applications including 1G, 10GBASE-T/KR/LR/SR, and FCoE

Procurement Notes

Verify the specific ordering suffixes against the datasheet Part Identification table to ensure correct configuration. The 'C' suffix indicates LVCMOS output, while 'HC' denotes HCSL; verify if the requested model matches the required output format. Confirm packaging options such as Tape & Reel quantities (1k or 3k pcs/reel). Ensure temperature grade requirements align with the available options (-20°C to +70°C, -40°C to +85°C, or -40°C to +105°C).

Selection Notes

Select this component for designs requiring a small footprint (3.2 x 2.5 mm) and low power consumption. The HCSL output format is suitable for high-speed signaling with good noise margins. Consider the operating temperature range when choosing between the E, L, or X suffixes. Verify that the system supply voltage falls within the 2.25V to 3.6V range. For frequencies other than standard options, contact the manufacturer directly.

Part Context

This part belongs to the AB-557-03 series of ultra-miniature SMD clock generators. The series offers mixed output formats including LVPECL, LVDS, and LVCMOS. It is designed as a drop-in replacement for traditional crystal-based oscillators, providing solid-state reliability and eliminating the need for external crystals.

Replacement Considerations

For frequencies other than 100MHz, consider using the ASEMDxx series. Direct replacements should match the 14-QFN package and supply voltage range. Verify output compatibility if substituting with different output formats like LVCMOS or LVPECL.
