Oscillators 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 footprint matches your PCB layout constraints. Check for any specific environmental or export classification requirements relevant to your region.

Oscillators Selection Notes

Select this component when a 33.9451 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage and power-down feature for low-power applications. Evaluate the small 2.0x1.6 mm package size for space-constrained designs. Verify that the standard XO performance meets your jitter and stability needs.

Oscillators Part Context

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

Oscillators Replacement Considerations

Direct substitutes must match the 33.9451 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent electrical characteristics such as phase noise and stability. Cross-reference with other manufacturers offering similar low-profile oscillators with power-down functionality.
