• Consumer electronics with space constraints

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues during integration.

Selection Notes

Select this component when a precise 13.52915 MHz clock source is required in a minimal footprint. The choice is driven by the need for low-power standby modes and compatibility with 1.8V logic families. Consider the 4-SMD package for automated assembly processes where board space is limited.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based timing solutions. The series offers various frequencies within a standardized small outline package, catering to industries demanding reliable frequency control components with consistent performance characteristics across different operating temperatures.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts and electrical specifications but different frequencies, such as the 18QHTF21-13.560-PD. Cross-referencing with generic 2.0x1.6mm LVCMOS oscillators requires careful verification of voltage and output drive strength.
