Conditions/Comments
Voltage required at FAIL for
IBIAS and IMOD to turn off
when FAIL asserted
Voltage required at FAIL for
IBIAS and IMOD to stay on
when FAIL asserted
2 mA < IBIAS < 11 mA
11 mA < IBIAS < 50 mA
50 mA < IBIAS < 100 mA
10 mA < IBIAS < 100 mA
When IBIAS = IMOD = 0
1 Temperature range: –40°C to +85°C.
2 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.
3 Guaranteed by design and characterization. Not production tested.
4 Measured into a single-ended 15 Ω load using a K28.5 pattern at 2.5 Gbps, shown in Figure 2.
5 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.
6 Measured into a differential 30 Ω load using a K28.5 pattern at 4.25 Gbps, as shown in Figure 3.
7 Measured into a differential 30 Ω load using a K28.5 pattern at 2.7Gbps, as shown in Figure 3.
8 When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.
9 Guaranteed by design. Not production tested.
10 IBIAS/IBMON ratio stability is defined in SFF-8472 Revision 9 over temperature and supply variation.
11 See the ICC minimum for power calculation in the Power Consumption section.
12 All VCC pins should be shorted together.
