• Embedded control units with low-power operational requirements

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application circuit before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern design to guarantee proper solder joint integrity and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a fixed 32.50794 MHz reference is required with minimal power usage. The LVCMOS output ensures direct interfacing with standard logic families without additional buffering. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical for extending operational life.

Oscillators Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series is characterized by small form factors and standardized output levels. The '18' prefix typically indicates the 1.8V supply voltage requirement, while 'PD' denotes the inclusion of a power-down control pin for enhanced energy efficiency in portable applications.

Oscillators Replacement Considerations

Direct replacements must match the 32.50794 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the power-down function. Cross-reference with other manufacturers offering identical electrical specifications and thermal characteristics to ensure functional equivalence.
