Procurement Notes
Verify the specific suffix OE against the manufacturer's datasheet to confirm the enable/disable feature and output type. Ensure the operating temperature range meets system requirements. Cross-reference the part number with official Mercury Electronics documentation to avoid confusion with similar variants lacking the enable function or differing in package style.
Selection Notes
Select this component when a 60.8875 MHz reference is required in space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital circuits. The enable pin allows for dynamic power management. Verify that the load capacitance and stability specifications align with the target microcontroller or FPGA input requirements.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small form factor. The series is characterized by its use of quartz crystal technology for stable frequency generation. The 'OE' suffix typically denotes specific electrical characteristics or packaging options defined by the manufacturer for this particular variant.
Replacement Considerations
Direct replacements must match the 60.8875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify enable/disable functionality compatibility. Consult Mercury Electronics for approved cross-references or updated part numbers.
