Oscillators Procurement Notes

Verify the specific voltage suffix (1.0V) and temperature grade (-40C+85C) against project requirements. Confirm package compatibility with PCB footprint specifications. Ensure supply chain sources provide authentic River Eletec components to guarantee timing accuracy and reliability standards.

Oscillators Selection Notes

Select this component when a 38.4 MHz clock source is required with strict 20 ppm stability limits. Choose the 1.0V variant for low-voltage CMOS logic compatibility. Consider the 4-SMD no-lead package for space-constrained designs requiring automated assembly processes.

Oscillators Part Context

This part belongs to the FCXO-07 series of surface-mount crystal oscillators from River Eletec Corporation. The series focuses on miniaturization and precision timing solutions. Variants differ primarily by supply voltage, frequency tolerance, and operating temperature ranges while maintaining the same physical footprint.

Oscillators Replacement Considerations

Direct substitutes include FCXO-07F38.40MVdd0.9V20ppm-40C+85C-B and FCXO-07F38.40MVdd1.2V20ppm-40C+105C-B. Verify voltage level compatibility before substitution. Check if extended temperature ranges or different supply voltages meet system constraints.
