Crystals Procurement Notes

Verify the specific tolerance and stability ratings against project requirements, as datasheet variations exist regarding ppm specifications. Confirm the exact package footprint matches the PCB design constraints. Ensure the operating temperature range meets environmental conditions. Cross-reference the manufacturer part number with official TXC documentation to confirm current production status and RoHS compliance details before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 48 MHz reference signal is required in a compact surface-mount form factor. The 12 pF load capacitance must match the oscillator circuit design parameters. Consider the 50 Ohm ESR value for impedance matching within the host circuit. Evaluate the -20°C to +70°C temperature range against operational environments. Compare against alternative crystals if tighter frequency stability or wider temperature ranges are necessary.
