Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure that the 1.8V supply voltage aligns with the target system's power rails. Confirm that the enable pin configuration matches the control logic available in the design. Cross-reference the package dimensions with the PCB footprint to ensure mechanical compatibility. Validate the operating temperature range against the environmental conditions of the intended application.
Selection Notes
Select this component when a low-profile oscillator with integrated enable control is required. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V supply requirement when designing power distribution networks. The small form factor makes it suitable for portable or densely populated circuit boards. Evaluate the thermal performance within the specified -40°C to +85°C range.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series offers various frequencies and supply voltages. Mercury Electronics has a long history in manufacturing crystal oscillators and filters. This specific model represents a standard XO variant optimized for modern digital applications.
Replacement Considerations
Compatible substitutes include the 18QHTF21-75.630-OE and 18QHTF21-44.200-OE from the same manufacturer. These parts share identical packaging and electrical characteristics except for their operating frequencies. Verify that the system can accommodate the different frequency outputs before substitution.
