Oscillators Procurement Notes

Verify the specific operating temperature range 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 footprint matches your PCB layout constraints. Cross-reference the part number with official manufacturer documentation to confirm current production status and availability.

Oscillators Selection Notes

Select this component when a 25.2 MHz frequency is required with low voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the thermal performance within the specified operating temperature range. Assess the physical dimensions of the 4-SMD package against available board real estate. Compare power consumption metrics between active and standby modes for efficiency optimization.

Oscillators Part Context

This model belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down feature. This specific variant targets applications needing stable timing at 25.2 MHz with minimal power usage in a small form factor.

Oscillators Replacement Considerations

Direct substitutes must match the 25.2 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics. Check for equivalent standby functionality. Consult manufacturer cross-reference lists for validated alternatives.
