Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for any specific handling instructions regarding electrostatic discharge protection during installation.

Oscillators Selection Notes

Select this model when a 13.59 MHz clock source is required with minimal power consumption. The 1.8V operating voltage makes it suitable for modern low-voltage digital logic families. Consider the physical size constraints of the 2.0x1.6mm package when designing dense PCB layouts. The power-down feature is advantageous for devices with intermittent usage patterns to extend battery life.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and package styles. The 'PD' suffix indicates the inclusion of a power-down control pin. These oscillators are engineered for reliability in consumer electronics and industrial applications where space and power efficiency are critical design factors.

Oscillators Replacement Considerations

Direct replacements must match the 13.59 MHz frequency, 1.8V supply, and LVCMOS output. Verify that substitute components support the same 4-SMD no-lead package outline. Ensure equivalent performance in terms of phase noise and stability if specified in the original design requirements.
