Notes:
9. SiTime recommends electrical connection to VDD. Use narrow traces (e.g. 4 to 6 mil) to avoid significant heat dissipation through these pads.
10. I2C address is a factory programmable option.
11. 0.1 μF capacitor in parallel with a 10 μF capacitor are required between VDD and GND.
12. Connecting DNC pin to VDD or ground may cause the device to malfunction.
