550AB000131DGR

Oscillators Overview

The Skyworks Solutions Inc. 550AB000131DGR is a Voltage-Controlled Crystal Oscillator (VCXO) from the Si550 series, operating at a fixed frequency of 669.32658 MHz. It features an LVPECL output format and operates on a 3.3V supply voltage with a maximum current consumption of 130mA. The device supports Enable/Disable functionality and offers a frequency stability of ±20ppm with an Absolute Pull Range (APR) of ±30ppm. It is housed in a compact 6-SMD, No Lead package measuring 7.00mm x 5.00mm x 1.80mm and functions within a temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Supports differential or single-ended output configurations for flexible system integration
• Includes hardware enable/disable control for power management optimization
• Utilizes a crystal base resonator for precise frequency generation

Oscillators Applications

• Telecommunications infrastructure equipment requiring stable clock signals
• Datacom and telecom modules needing low phase noise oscillators
• High-speed digital systems utilizing LVPECL interface standards

Oscillators Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure the ordering part number matches the exact frequency and output requirements, as minor suffix variations may indicate different packaging or testing criteria. Cross-reference the datasheet for any recent product change notices affecting this specific variant.

Oscillators Selection Notes

Select this component when a fixed frequency of 669.32658 MHz is required with LVPECL outputs. Consider the ±30ppm APR if frequency tuning capability is needed. Evaluate the 130mA supply current against system power budgets. Confirm that the 7x5mm SMD footprint fits the PCB layout constraints compared to other Si550 variants.

Oscillators Part Context

This oscillator belongs to the Si550 family of VCXOs designed for high-performance applications. It shares the standard 6-SMD package dimensions with other models in the series but differs in its specific programmed frequency and output type. The device is distinct from dual-frequency variants like the 552 series, offering a single fixed frequency operation optimized for specific timing applications.

Oscillators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 550AE000131DG and 550ME000131DG. Verify compatibility regarding the reel packaging suffix ('R') versus tray packaging ('G') before substitution.
