1 Temperature range: −40°C to +85°C.

2 Measured into a 15 Ω load (22 Ω resistor in parallel with digital scope 50 Ω input) using a 11110000 pattern at 2.5 Gbps, shown in Figure 2.

3 Guaranteed by design and characterization. Not production tested.

4 When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.

5 Guaranteed by design. Not production tested.

6 IBIAS/IBMON ratio stability is defined in SFF-8472 revision 9 over temperature and supply variation.

7 ICC minimum for power calculation (see the Power Consumption section).

8 All VCC pins should be shorted together.
