Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 25.00075 MHz clock source is needed with low power consumption capabilities. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6 mm package size for space-constrained designs. Evaluate the need for standby functionality to optimize overall system power usage during idle periods.

Oscillators Part Context

This part belongs to the QHTF series of high-frequency oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down feature. These components are designed for applications requiring stable clock signals in minimal space.

Oscillators Replacement Considerations

Direct substitutes may include other 25.00075 MHz LVCMOS oscillators in a 4-SMD 2.0x1.6mm package with 1.8V operation. Verify pinout compatibility and electrical parameters such as phase noise and jitter before substitution. Consult manufacturer cross-reference lists for approved alternatives.
