Temperature range is from −40°C to +85°C.
Measured into a single-ended 15 Ω load (22 Ω resistor in parallel with digital scope 50 Ω input) using a 1111111100000000 pattern at 2.5 Gbps, shown in Figure 2.
Guaranteed by design and characterization. Not production tested.
Measured into a single-ended 15 Ω load using a K28.5 pattern at 2.5 Gbps, shown in Figure 2.
Measured into a differential 30 Ω (43 Ω differential resistor in parallel with a digital scope of 50 Ω input) load using a 1111111100000000 pattern at 4.25 Gbps, as
shown in Figure 3.
Measured into a differential 30 Ω load using a K28.5 pattern at 4.25 Gbps, as shown in Figure 3.
Measured into a differential 30 Ω load using a K28.5 pattern at 2.7 Gbps, as shown in Figure 3.
When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows into 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.
