Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 27.12015 MHz clock source is required with low voltage operation. Consider the LVCMOS output type for direct interfacing with standard digital logic families. Evaluate the small 2.0x1.6mm package size against available board space constraints. Verify thermal operating range suitability for the intended environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The suffix OE indicates the presence of an enable pin feature, distinguishing it from basic continuous-output variants within the same package family.

Oscillators Replacement Considerations

Compatible substitutes include other 18QHTF21 series parts with identical frequency and package, such as 18QHTF21-27.12000-OE if minor frequency deviation is acceptable. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators with enable functionality, ensuring voltage and pinout compatibility.
