• Portable electronic devices requiring low power consumption

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific environmental certifications required for your application region.

Oscillators Selection Notes

Select this model when a precise 30.5 MHz reference is needed with minimal power usage. The small 2.0x1.6mm form factor suits space-constrained designs. Consider the LVCMOS interface compatibility with your target microcontroller or FPGA. Evaluate the need for active power-down control to extend battery life in portable applications.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down pin for standby management. These components are designed for high reliability in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 30.5 MHz frequency, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility for the power-down function. Cross-reference with other Mercury QHTF variants if voltage or frequency adjustments are permissible.
