IDT 89HPES12N3A Data Sheet
This section describes the sequence in which various voltages must be applied to the part during power-up to ensure proper functionality. For the
1. V
2. V
3. V
When powering up, each voltage level must ramp and stabilize prior to applying the next voltage in the sequence to ensure internal latch-up issues
Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 13
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
