Notes:
7. In OE mode, a pull-up resistor of 100 kΩ or less is recommended if Pin 1 is not externally driven. If Pin 1 needs to be left floating, use the NC option.
8. Pin 1 voltage should not exceed device VDD or fall lower than device GND. Either of these conditions may lead to frequency sh ifts larger than
specified limits.
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. 0.1 μF capacitor in parallel with a 10 μF capacitor are required between VDD and GND.
11. Connecting DNC pin to VDD or ground may cause the device to malfunction.
