Temperature range: –40°C to +85°C.
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.
Guaranteed by design and characterization. Not production tested.
When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.
Guaranteed by design. Not production tested.
IBIAS/IBMON ratio stability is defined in SFF-8472 revision 9 over temperature and supply variation.
