Crystals Procurement Notes

Verify the specific suffix 'EEC' against official TXC documentation to confirm exact electrical tolerances and packaging specifications, as distributor listings may vary. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm that the required frequency stability meets the system design constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 40 MHz reference with ±10 ppm stability is required in a small form factor. The 10 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range against environmental conditions. Compare against similar 7M series parts if different temperature ranges or package sizes are needed.
