46.9.1 UTMI PLL Characteristics
46.10 I/Os
Criteria used to define the maximum frequency of the I/Os:
• Output duty cycle (40%-60%)
• Minimum output swing: 100 mV to VDDIO - 100 mV
• Addition of rising and falling time inferior to 75% of the period
Notes: 1. 3.3V domain: V
VDDIOP
from 3.0V to 3.6V, maximum external capacitor = 40 pF
2. 1.8V domain: V
VDDIOP
from 1.65V to 1.95V, maximum external capacitor = 20 pF
