Sideband Signals DC Specifications (Required)

The four sideband signals defined for the 12VHPWR connector DC Specifications are shown in Table 3-7. This is the requirement defined by the PCIe* CEM 5.0 Specification for the Add-in Cards.

Table 3-7. PCI Express* 12VHPWR Connector – Sideband Signal DC Specifications

Symbol	Parameter	Conditions	Min	Max
V_HMAX	Max High Voltage any Pin			3.3 V +0.5 V
V_IL	Input Low Voltage		-0.2 V	+0.8 V
V_IH	Input High Voltage		+2.0 V	3.3 V +0.2 V
V_OL	Output Low Voltage	7.0 mA	-0.2 V	+0.5 V
V_OH	Output High Voltage (refer note)	4.0 mA	+2.4 V	3.3 V + 0.2 V
R_PULL-UP	Pull-up / Pull-down Resistance tolerance		-10%	+10%

Note:For Open-Collector/Open Drain Signal CARD_PWR_STABLE output a pull-up is required. There is no VOH specification for this signal.
