554AH000322DGR

Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 554AH000322DGR is a quad-frequency low-jitter voltage-controlled crystal oscillator (VCXO) from the Si554 series. It operates on a single 3.3V supply and features an LVPECL output format with enable/disable functionality. The device utilizes DSPLL circuitry to provide precise clock signals across four selectable frequencies: 569.1964 MHz, 690.5692 MHz, 693.483 MHz, and 704.3806 MHz. It offers frequency stability of ±20 ppm and functions within a temperature range of -40°C to +85°C. The component is housed in an 8-SMD, no-lead package measuring 7.00mm x 5.00mm.

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration. The 'DG' variant typically denotes tube packaging, while 'DGR' indicates reel packaging. Confirm that the selected package matches your automated assembly requirements. Cross-reference the full part number against official Skyworks documentation to validate availability and lead times before finalizing procurement plans.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when multiple specific high-frequency outputs are required from a single footprint. Ensure the system design supports LVPECL signaling levels and the 3.3V supply rail. Verify that the ±20 ppm stability meets the phase noise and jitter requirements of the target application. Consider the thermal environment to ensure operation remains within the specified -40°C to +85°C range.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Si554 family of quad-frequency VCXOs designed for demanding clocking applications. It replaces older discrete solutions by integrating multiple frequency options into a compact surface-mount package. The series is engineered for high reliability and low phase noise, making it suitable for modern high-bandwidth data transmission systems where timing integrity is critical.

Pin ConfigurableSelectable Oscillators Replacement Considerations

The parameter-equivalent substitute is 554AH000322DG. This alternative provides identical electrical specifications and pinout compatibility. Verify that the packaging difference between the DG and DGR suffixes aligns with manufacturing needs.
