Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints to ensure proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 37.5 MHz clock source is required with minimal power usage during idle states. The LVCMOS output ensures compatibility with standard logic families. Consider the small form factor for space-constrained designs. Verify operating temperature range specifications if the application involves extreme environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and standby capabilities. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 37.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators with standby functions.
