Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain oscillator performance. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to ensure proper soldering and mechanical stability.

Oscillators Selection Notes

Select this model when a fixed 41.424 MHz frequency is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and the availability of a standby control signal if power management is critical. Evaluate the thermal environment to ensure operation within the specified temperature range. Compare package size constraints against alternative oscillators if space is limited.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and low-voltage operation.
