552DD000123DG

Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 552DD000123DG is a Voltage-Controlled Crystal Oscillator (VCXO) from the Si552 series, designed for dual-frequency operation within the 10 MHz to 1.4 GHz range. It features a CML output format and operates on a 3.3 V supply voltage with a minimum of 2.97 V and maximum of 3.63 V. The device supports a load capacitance of 15 pF and draws a current rating of 130 mA. Encased in a 7 mm x 5 mm SMD/SMT package with dimensions of 7 mm length, 5 mm width, and 1.8 mm height, it functions reliably between -40°C and +85°C.

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific output frequency configuration against system requirements before procurement. Confirm that the CML output interface matches the receiving circuit's input specifications. Ensure the power supply provides stable 3.3 V within the 2.97 V to 3.63 V operating range. Check lead times as production cycles may vary. Validate thermal management capabilities for the -40°C to +85°C operating temperature range.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when dual-frequency capability is required within the 10 MHz to 1.4 GHz spectrum. Choose the CML output format if differential signaling compatibility is necessary. Consider the 7 mm x 5 mm footprint for PCB layout constraints. Evaluate the 130 mA current draw against available power budget. Compare against other Si552 variants if CMOS or LVPECL outputs are preferred instead.

Pin ConfigurableSelectable Oscillators Part Context

This part belongs to the Skyworks Si552 family of VCXOs, which offers various output formats and frequency ranges. The 552DD000123DG specifically targets applications needing dual-frequency support with CML outputs. It shares the standard 7 mm x 5 mm package with other members of the series but differs in electrical characteristics and pin configurations.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Check Skyworks documentation for direct substitutes within the Si552 series that match the dual-frequency requirement and CML output. Verify pin-to-pin compatibility if replacing in existing designs.
