Procurement Notes
Verify the specific suffix OE against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with 1.8V supply rails and LVCMOS logic levels. Cross-reference the 100.196 MHz frequency requirement with system specifications before procurement.
Selection Notes
Select this component when a low-profile 2.0x1.6mm oscillator is required for 1.8V digital circuits. The LVCMOS output is suitable for direct interfacing with standard logic inputs. Consider the enable feature if power management during idle states is necessary for the application design.
Part Context
This part belongs to the Mercury Electronics SMD oscillator series, specifically utilizing the QHTF21 form factor. The series typically offers various frequencies within a standardized footprint. The 18QHTF21 designation indicates the package type and series family, while the numeric suffix defines the specific operating frequency.
Replacement Considerations
Direct substitutes include other 100.196 MHz LVCMOS oscillators in 4-SMD 2.0x1.6mm packages from different manufacturers. Verify that replacement parts support 1.8V operation and have compatible enable pin configurations to ensure functional equivalence.
