Oscillators Procurement Notes

Verify the specific suffix 'MDB' against the manufacturer's official part numbering system to confirm voltage, tolerance, and temperature grade specifications. Ensure compatibility with the target PCB footprint and reflow soldering profiles. Cross-reference the datasheet revision date to confirm current manufacturing status and compliance certifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 14.31818 MHz reference is required for CMOS-compatible circuits. Consider the +/-25 ppm stability and industrial temperature range (-40°C to +85°C) as critical parameters for environmental resilience. Evaluate the 5.0x3.2 mm package size against available board space constraints and compare power consumption requirements with alternative oscillator technologies if low power is a primary design driver.
