• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and output specifications. Confirm that the OE suffix aligns with the required enable/disable feature set. Cross-reference the part number with the latest datasheet to validate package dimensions and operating temperature ranges before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature allows for power management in battery-operated devices. Ensure the 4-SMD footprint fits the PCB layout constraints. Verify that the 59.7 MHz frequency meets the system timing requirements without needing external dividers.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor timing solutions. The series typically offers various frequencies within a standardized package profile. Mercury Electronics leverages decades of quartz crystal manufacturing expertise to produce these components, emphasizing reliability in frequency control applications.

Replacement Considerations

Direct substitutes must match the 59.7 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check equivalent parts from other manufacturers for pinout compatibility and electrical parameter alignment. Verify that any replacement also supports the enable/disable control function if required by the design.
