554AC000361DG

Overview

The Skyworks Solutions Inc. 554AC000361DG is a pin-configurable VCXO oscillator from the Si554 series, housed in an 8-SMD package measuring 7.00mm x 5.00mm with a height of 1.80mm. It operates on a 3.3V supply voltage and supports output frequencies including 622.08MHz, 644.53125MHz, 666.51429MHz, and 669.32658MHz. The device features LVPECL output format, ±50ppm frequency stability, and an operating temperature range of -40°C to 85°C. Maximum supply current is 130mA, with a maximum disabled current of 75mA.

Feature Summary

• Pin-configurable architecture allows for flexible integration into various system designs without custom mask sets.
• Supports multiple high-frequency outputs within the 600MHz+ range suitable for demanding digital interfaces.
• Includes enable/disable functionality to manage power consumption during inactive periods.

Applications

• High-speed data communication systems requiring precise clock generation
• Telecommunications infrastructure equipment
• Test and measurement instruments

Procurement Notes

Verify that the specific part number matches the required output frequency and logic family before ordering. Confirm that the 8-SMD package dimensions align with the target PCB footprint. Ensure the design accommodates the specified 3.3V supply requirements and thermal dissipation needs for the -40°C to 85°C operating range. Check for any recent product change notices regarding pinout or electrical characteristics.

Selection Notes

Select this component when a low-jitter, high-frequency VCXO with LVPECL outputs is required in a compact surface-mount form factor. Consider the Si554 series for its pin-configurable nature, which reduces inventory complexity compared to fully custom solutions. Evaluate the ±50ppm stability against system timing budgets. Compare power consumption metrics if battery life or thermal management is a critical constraint in the application environment.

Part Context

This oscillator belongs to the Skyworks Si554 family of pin-configurable crystal oscillators. These devices are designed to offer the performance of custom silicon with the flexibility of standard components. The 554AC variant specifically utilizes LVPECL outputs, distinguishing it from CMOS or CML variants within the same physical package family.

Replacement Considerations

The 554AC000361DGR is a parameter-equivalent alternative available in tape and reel packaging. Verify that the reel quantity and handling requirements match production needs. No other direct substitutes are documented in the provided source material.
