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 12 kHz to 20 MHz.

5.

Measured with Agilent TDR module.

6.

10% to 90% rise and fall times.
