554CC000378DG

Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 554CC000378DG is a CMOS Voltage-Controlled Crystal Oscillator (VCXO) from the Si554 series, housed in an 8-SMD, no-lead package measuring 7.00 mm x 5.00 mm x 1.80 mm. It operates on a single 3.3 V supply with a maximum current draw of 98 mA and features a load capacitance of 15 pF. The device supports four specific output frequencies: 27 MHz, 50 MHz, 74.175824 MHz, and 74.25 MHz, with a frequency stability of ±50 ppm. It functions within a temperature range of -40°C to +85°C and includes enable/disable functionality.

Pin ConfigurableSelectable Oscillators Feature Summary

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency variant required during ordering, as the part number corresponds to a fixed set of four outputs. Confirm that the 3.3 V supply voltage aligns with the target circuit design. Ensure the 8-SMD package dimensions fit the available PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when a precise CMOS output is required for digital interfaces rather than differential signaling. Consider the ±50 ppm stability specification against system jitter requirements. Evaluate the 98 mA maximum current consumption against thermal constraints. Compare the fixed frequency options against alternative models if other standard rates are needed.
