Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this model when a precise 36.667 MHz clock source is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage constraint to ensure compatibility with low-power logic families. The integrated standby feature makes it suitable for battery-operated or power-sensitive designs where idle power reduction is critical.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series is characterized by small form factors and low voltage operation. The 'PD' suffix typically indicates the inclusion of a power-down pin or function, distinguishing it from standard continuous-operation variants within the same family.
