Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance specifications against your circuit design requirements before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD package matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your specific environmental conditions.

Oscillators Selection Notes

Select this component when a low-voltage, small-form-factor oscillator is required for digital interfaces. The LVCMOS output ensures direct compatibility with standard logic families without additional buffering. Consider the power-down feature if battery life or thermal management is critical. Verify that the 18.0896 MHz frequency meets the specific timing needs of your microcontroller or communication protocol.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control pin, allowing for active standby modes. This family is designed for applications prioritizing size reduction and power efficiency.

Oscillators Replacement Considerations

Direct substitutes within the same series include other 18QHTF21 variants with matching 1.8V operation and LVCMOS outputs. Check for identical package dimensions (2.0x1.6 mm) and pinout configurations to ensure mechanical compatibility. Frequency-specific replacements must match the 18.0896 MHz requirement exactly. Verify equivalent electrical characteristics such as phase noise and stability if performance sensitivity is high.
