Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply voltage aligns with the host circuit's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications. Cross-reference the part number suffix with official documentation to confirm availability and exact electrical characteristics.

Oscillators Selection Notes

Select this component when a precise 36.62109 MHz clock signal is required for LVCMOS-compatible digital circuits. The choice is driven by the need for a low-voltage 1.8V operation mode and the integration of enable/disable controls. Consider the physical dimensions of the 4-SMD package for space-constrained designs. Evaluate the thermal performance within the specified operating temperature range relative to the application environment.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics SMD XO series, characterized by small form factors and low power consumption. The '18' prefix typically indicates the 1.8V supply voltage requirement, while 'QHTF' denotes the specific product line configuration. This series is engineered for high-volume consumer and industrial electronics where size and energy efficiency are critical constraints.

Oscillators Replacement Considerations

Direct substitutes must match the 36.62109 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters such as jitter and phase noise if applicable. Consult manufacturer cross-reference lists for equivalent parts from other suppliers offering identical specifications.
