Oscillators Procurement Notes

Verify the specific suffix 'OE' against official datasheets to confirm enable/disable capabilities and voltage levels. Ensure the 4-SMD footprint matches the target PCB layout. Confirm that the 1.8V supply requirement aligns with the system design before procurement.

Oscillators Selection Notes

Select this component when a low-profile surface mount oscillator with enable control is required. Consider the 1.8V supply constraint and ±50ppm stability specification relative to system requirements. Evaluate the 23mA current draw against available power budgets.

Oscillators Part Context

This part belongs to the Mercury QHT series of quartz crystal oscillators. The series utilizes surface mount technology and covers various frequencies. Mercury Electronic has specialized in frequency control products since 1973, offering both leaded and surface mount options.

Oscillators Replacement Considerations

Cross-reference with other 39.65 MHz LVCMOS oscillators in 4-SMD packages. Verify pinout compatibility and electrical specifications such as supply voltage and current consumption before substitution.
