Crystals Procurement Notes

Verify the specific suffix BGBK against official TXC documentation to confirm exact electrical parameters such as ESR and load capacitance. Ensure the selected variant matches the required temperature range and frequency tolerance for the target application environment. Cross-reference the package dimensions with PCB footprint libraries to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a 27 MHz fundamental crystal with ±50 ppm stability is required. Consider the 60 Ohm ESR value for oscillator circuit design to ensure proper startup conditions. The 20 pF load capacitance must align with the host system's capacitive requirements. Verify that the -20°C to +70°C range meets the operational environmental constraints.
