• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the LVCMOS output swing is compatible with the receiving logic inputs to guarantee reliable signal integrity and proper operation within the electronic assembly.

Selection Notes

Select this component when a precise 13.234375 MHz clock source is required for low-voltage digital systems. The choice is driven by the need for a standard XO with enable capabilities to manage power consumption. Consider the small form factor suitable for space-constrained PCB layouts and ensure the operating temperature range meets the environmental conditions of the intended deployment scenario.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options in a consistent 4-SMD footprint. This specific model provides a unique frequency point for applications requiring exact timing synchronization without the complexity of programmable clocks or higher voltage requirements found in other series variants.

Replacement Considerations

Direct substitutes must match the 13.234375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other manufacturers offering identical specifications to ensure functional equivalence in the final design.
