1. Measured across P to N with 400 mV bias.
2. Thevenin impedance is calculated based on independent P and N as measured at 50% of V
DDI
.
3. For 50Ω/75Ω/150Ω cases, the nearest supported values of 40Ω/60Ω/120Ω are used.
4. Measured at 50% of V
DDI
.
5. Supported terminations vary with the I/O type regardless of V
DDI
nominal voltage. Refer to Libero
for available combinations and default settings.
6. When V
ICM
complies with more than one range, use the maximum percentage tolerance of the
two ranges.
