Procurement Notes
Verify the specific suffix and voltage rating against project requirements to ensure compatibility with target logic levels. Confirm package dimensions match the designated footprint on the printed circuit board. Check manufacturer documentation for operating temperature range specifications relevant to the intended environment.
Selection Notes
Choose this oscillator when a low-voltage 1.8V supply is available and space constraints require a small SMD form factor. Consider the enable pin requirement if dynamic power saving is necessary. Ensure the LVCMOS output swing aligns with the input thresholds of the receiving microcontroller or FPGA.
Part Context
This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature oscillators. The series typically offers various frequencies and voltage options within similar physical footprints. The OE suffix indicates specific operational characteristics defined by the manufacturer for this variant.
Replacement Considerations
Direct substitutes must match the 13.5425 MHz frequency, 1.8V supply, and 4-SMD No Lead package. Verify that alternative components support LVCMOS outputs and include enable/disable functionality to maintain system power management strategies.
