Notes:

1. Non condensing.

2. AC coupled.

3. Into 100 ohm differential termination.

4. 20 – 80 %

5. LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.

6. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and ΔDJ.
