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 PCB footprint matches the 2.0x1.6mm package dimensions to prevent assembly issues. Check for any specific reflow soldering profile recommendations provided in the official datasheet to maintain component integrity during manufacturing processes.

Oscillators Selection Notes

Choose this model when a small form factor and low voltage operation are critical constraints. The LVCMOS interface ensures broad compatibility with standard digital logic families. Consider the power-down feature if battery life or thermal management is a priority. Verify that the 16.5888 MHz frequency meets the exact timing needs of the target application, as alternative frequencies may be available within the same series.

Oscillators Part Context

This component belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series is characterized by its small physical size and low operating voltage, making it suitable for modern miniaturized electronics. The 'PD' suffix typically indicates the inclusion of a power-down control pin, allowing for active standby modes to reduce overall system power usage compared to continuously running oscillators.

Oscillators Replacement Considerations

Direct substitutes include other 16.5888 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Ensure replacement parts match the 1.8V supply requirement and pinout configuration. Verify that the replacement maintains similar frequency stability and phase noise characteristics to avoid signal integrity issues in sensitive timing circuits.
