Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.
Selection Notes
Select this component when a standard frequency reference is required for low-voltage digital interfaces. Consider the enable/disable feature if power conservation is necessary during idle states. Verify that the operating temperature range meets the environmental conditions of the intended application environment.
Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies within the LVCMOS logic family. These components are designed for general-purpose timing applications where stable clock signals are essential for synchronous digital circuitry.
Replacement Considerations
Direct substitutes must match the 101.750 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications before substitution.
