Note 1. Actual value is adjustable. Values in this table require VADJ[2:0] = 4 (011b):

--RCVR2_VADJ: USBC1 MSR 51600008h[16:14] and USBC2 MSR 51200008h[16:14];

--(RCVR1_VADJ: USBC1 MSR 51600008h[7:5] and USBC2 MSR 51200008h[7:5].

The single ended receiver incorporates hysteresis for more reliable operation.

Under any mode of operation, the USB inputs do not meet the requirements of “Figure 7-1 Maximum Input Wave-

form For USB Signaling” from the USB Specification v1.1. The maximum voltage can not exceed the value above.

Note 2. USB v1.1 compliance is achieved with external crimp protection diodes.

Note 3. The following SMB I/Os are limited to an input high max of VIO: FUNC_TEST, SMB_CLK, and SMB_DATA.

Note 4. This parameter is sometimes referred to as TRI-STATE leakage.

Note 5. VCORE and VCORE_VSB = 0, VIO and VIO_VSB = 0, TCASE = All.

Note 6. AVDD_USB from 0 to AVDD_USB_MAX.

Note 7. No pull-ups/downs on PCI, IDE, and SMB I/O cell types.
