Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compliance with RoHS and REACH regulations. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint requirements. Check for any recent updates to the frequency tolerance or ESR specifications before finalizing procurement orders.

Crystals Selection Notes

Select this component when a stable 76.8 MHz reference is required for space-constrained applications. The 9.9 pF load capacitance must match the oscillator circuit design parameters. Ensure the 80 Ohm ESR is compatible with the driving circuitry to prevent overdriving or failure. Consider the ±20 ppm stability requirement relative to system timing accuracy needs.
