Oscillators Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the operational range. Ensure the PCB footprint matches the 4-SMD no-lead dimensions to prevent mounting issues during assembly.
Oscillators Selection Notes
Select this component when a fixed 41.657 MHz reference is required for LVCMOS-compatible digital logic. Consider the 1.8V operating voltage constraint and the need for power-down functionality. Evaluate the thermal performance and size constraints of the 4-SMD package relative to the available board space.
Oscillators Part Context
This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and low-voltage support. The manufacturer specializes in quartz crystal products, providing reliable frequency control solutions for electronic systems.
Oscillators Replacement Considerations
Direct substitutes must match the 41.657 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications before swapping manufacturers.
