Note:
1. V
CCPECI
supplies the PECI interface. PECI behavior does not affect V
CCPECI
min/max specification.
2. It is expected that the PECI driver will take into account, the variance in the receiver input thresholds and consequently, be
able to drive its output within safe limits (-0.150 V to 0.275*V
CCPECI
for the low level and 0.725*V
CCPEC
to V
CCPECI
+0.150 V
for the high level).
3. The leakage specification applies to powered devices on the PECI bus.
4. One node is counted for each client and one node for the system host. Extended trace lengths might appear as additional
nodes.
5. Excessive capacitive loading on the PECI line may slow down the signal rise/fall times and consequently limit the maximum
bit rate at which the interface can operate.
