554AF000227DGR

Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 554AF000227DGR is a quad frequency low-jitter voltage-controlled crystal oscillator (VCXO) designed for high-performance timing applications. It operates within a frequency range of 10 MHz to 1.4 GHz and utilizes an LVPECL output format. The device functions at a nominal supply voltage of 3.3 V, with operational limits between 2.97 V and 3.63 V. It features a load capacitance of 15 pF and draws a maximum current of 98 mA. The component is housed in a compact 7 mm x 5 mm surface-mount package with a height of 1.8 mm, suitable for space-constrained designs.

Pin ConfigurableSelectable Oscillators Feature Summary

• Supports four selectable frequencies within the 10 MHz to 1.4 GHz range via pin configuration.
• Delivers differential LVPECL output signals for robust signal integrity.
• Operates on a standard 3.3 V power supply with defined minimum and maximum voltage thresholds.

Pin ConfigurableSelectable Oscillators Applications

• High-speed serial communication interfaces requiring precise clock generation
• Data acquisition systems needing stable voltage-controlled timing references
• Telecommunications equipment utilizing wide-band frequency synthesis

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency selection pins against your schematic design, as this quad-frequency variant requires hardware configuration to determine the operating band. Confirm that the LVPECL output compatibility matches your receiver inputs. Ensure the PCB layout accommodates the 7 mm x 5 mm footprint and maintains adequate clearance for thermal management during continuous operation at 3.3 V.

Pin ConfigurableSelectable Oscillators Selection Notes

Choose this model when a single component must support multiple frequency points across a wide spectrum without software reconfiguration. The LVPECL output is ideal for noise-sensitive environments compared to single-ended formats. Consider the 15 pF load capacitance requirement for external circuit matching. This part is suitable where physical space is limited but high-frequency stability up to 1.4 GHz is required.

Pin ConfigurableSelectable Oscillators Part Context

This component belongs to the Si554 series of pin-configurable oscillators from Skyworks Solutions. The series is engineered for applications demanding flexibility in frequency selection while maintaining low phase noise and jitter characteristics. The 554AF000227DGR specifically addresses needs for quad-frequency versatility in a standard surface-mount package.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct replacements within the same family include the 554PC000522DGR and 554AJ002404DGR. Note that these alternatives may differ in output format, such as CMOS or LVPECL variations, and current consumption ratings. Verify pin compatibility and output drive strength before substitution.
