Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 124.52 MHz frequency tolerance meets the application requirements before procurement.
Selection Notes
Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. The LVCMOS output is suitable for direct interfacing with standard digital inputs. Consider the enable feature if power conservation during idle states is necessary for the specific application environment.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-footprint oscillators. The series typically offers various frequencies and voltage options within the same package family, allowing designers to maintain consistent board layouts across different product variants while adjusting electrical parameters.
Replacement Considerations
Cross-reference with other 18QHTF21 series parts such as 18QHTF21-44.200-OE or 18QHTF21-8.300-OE for frequency changes. Verify that substitute components maintain the same 4-SMD package dimensions and 1.8V LVCMOS characteristics to ensure mechanical and electrical compatibility.
