Procurement Notes

Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct frequency and voltage specifications. Confirm that the LVCMOS output type matches your circuit requirements. Check the operating temperature range suitability for your specific environment. Ensure the 1.8V supply voltage aligns with your power design. Validate the package dimensions against your PCB footprint before procurement.

Selection Notes

Select this component when a 86.9175 MHz clock source is required with LVCMOS outputs. Consider the 1.8V supply constraint and enable/disable feature for power management needs. Evaluate the 4-SMD package size against available board space. Compare performance against other Mercury oscillators if different frequencies or voltages are needed. Ensure the standard XO type meets jitter and stability requirements for the application.

Part Context

This model belongs to the Mercury 18QHTF series of crystal oscillators. The series typically offers various frequencies with LVCMOS outputs and low voltage operation. Mercury Electronics specializes in quartz-based timing components. The 18QHTF series is designed for general electronic applications requiring reliable clock signals.
