- Digital signal processing systems
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues during manufacturing.
Selection Notes
Select this component when a precise 112.41 MHz reference is required for LVCMOS-compatible digital circuits. The choice is driven by the need for a low-profile surface-mount solution with power-down capabilities. Consider the operating temperature range and phase noise characteristics if the application involves sensitive timing requirements or high-frequency signal integrity.
Part Context
This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. The suffix OE indicates the enable/disable functionality. This model specifically targets applications needing a stable clock source in space-constrained electronic designs.
Replacement Considerations
Direct replacements must match the 112.41 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the enable pin. Cross-reference with other Mercury 18QHTF21 variants or industry-standard equivalents ensuring identical electrical parameters and mechanical footprint.
