554AH000464DGR

Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 554AH000464DGR is a pin-configurable Voltage-Controlled Crystal Oscillator (VCXO) operating within the 10 MHz to 1.4 GHz frequency range. It functions on a nominal 3.3 V supply voltage, with an operational range of 2.97 V to 3.63 V. The device features an LVPECL output format and utilizes a standard 8-pin SMD/SMT package measuring 7 mm x 5 mm x 1.8 mm. Designed for robust performance across industrial temperatures, it operates reliably between -40°C and +85°C. The component draws a maximum current of 117 mA and includes a load capacitance specification of 15 pF, making it suitable for high-frequency timing applications requiring precise frequency control.

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency and tuning curve parameters against the official datasheet before procurement, as the part number indicates a family member rather than a single fixed specification. Confirm that the LVPECL output format matches your circuit design requirements. Ensure the 7x5mm SMD footprint aligns with your PCB layout constraints. Check for RoHS compliance status in the latest documentation.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a wide frequency range up to 1.4 GHz is required alongside pin-selectable flexibility. It is appropriate for designs needing LVPECL outputs and operation at 3.3V. Consider the thermal range of -40°C to +85°C for environmental suitability. Compare against other Si554 series variants if different output formats or power consumption profiles are needed.

Pin ConfigurableSelectable Oscillators Part Context

This oscillator belongs to the Si554 series of VCXOs from Skyworks Solutions. The series is characterized by its ability to cover broad frequency ranges with a single package footprint. The 'AH' suffix typically denotes specific pin configurations or output types within this family, distinguishing it from other variants like the DG or DGR models which may have different electrical characteristics.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct substitutes within the same package and function include other members of the Si554 series such as the 554DD000732DG or 554AK000435DGR, provided their specific frequency and output format specifications match the application needs. Verify pin compatibility and electrical parameters before substitution.
