Oscillators Procurement Notes

Verify the specific suffix OE against your bill of materials to ensure correct frequency tolerance and package variant. Confirm that the 1.8V supply requirement aligns with your system power rails. Check datasheet specifications for operating temperature range and load capacitance requirements before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 29.4471 MHz clock signal is required with low-voltage LVCMOS outputs. Ensure the design accommodates the 1.8V supply constraint and utilizes the enable pin if power management is necessary. Verify footprint compatibility with the 4-SMD No Lead package during PCB layout.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of quartz crystal oscillators. The series provides various frequencies with LVCMOS outputs. The manufacturer specializes in frequency-control products including crystals, TCXOs, and VCTCXOs, established as a pioneer in the Taiwan crystal industry since 1973.

Oscillators Replacement Considerations
