NOTE:
1. This capacitance is supplied internally (no external cap is required).
2. When using an external reference clock source, this should be AC coupled through a 0.1 µF capacitor.
3. When using an external clock a small increase in jitter may be seen. For best performance a crystal is recommended.
4. Jitter bandwidth is from 12 kHz to 20 MHz.
5. Measured with TDR module.
6. 10% to 90% rise and fall times.
