Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a precise 86.56 MHz clock source is required for low-voltage digital circuits. The LVCMOS output ensures compatibility with standard logic families. Consider the enable pin if dynamic power control is necessary for the application. Verify thermal operating range suitability for the intended environment.
Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a small form factor. These components are designed for general timing applications where stable frequency generation is critical for synchronous digital systems.
Replacement Considerations
Direct substitutes must match the 86.56 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics to maintain board compatibility.
