Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this model when a 62.914 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the availability of standby control. Evaluate the 2.0x1.6mm package size against space limitations. Compare performance metrics such as phase noise and stability if available in official documentation to ensure suitability for the target application.

Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down feature. Mercury Electronics has a long history in quartz crystal manufacturing, providing frequency control products since 1973.

Replacement Considerations

Direct substitutes include other 62.914 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead packaging. Verify pinout compatibility and electrical specifications before substitution. Alternative models from the same manufacturer with different frequencies may share similar physical characteristics but require circuit adjustment.
