1. VOH is the single-ended high-output voltage.

2. The total DC sink/source current of all I/Os within a lane is limited as follows:

a. HSIO lane: 120 mA per 12 I/O buffers.

b. GPIO lane: 160 mA per 12 I/O buffers.

3. VOH_MAX is based on external pull-up termination (pseudo-open drain).

4. IOL/IOH units for impedance standards are in amps (not mA).

Note: Thevenin impedance is calculated based on independent P and N as measured at 50% of VDDI. For 50

Ω/75 Ω/150 Ω cases, the nearest supported values of 40 Ω/60 Ω/120 Ω are used.
