Notes:
1. Output Peak-to-Peak Differential Voltage specified as DOUT+ minus DOUT-. This measurement is made using a repeating 1010 pattern. Vop
amplitude can be adjusted with the program register.
2. Minimum data rate depends on the value of AC input coupling capacitance and input resistance which is 100 Ohms between the positive and
negative inputs.
3. Jitter measurement was carried out using a 3.3G BERT with a base jitter of 19ps for Deterministic Jitter and 0.97ps for Random Jitter. For eye
diagrams, please see application notes. Jitter Measurement is taken using a K28.5 pattern at 3.2Gbaud data rate.
