Clock Amplifier Module (CAMP) Electrical Characteristics
This section outlines the Clock Amplifier Module (CAMP) specific electrical characteristics. Table 19
shows clock amplifier electrical characteristics.
Table 17. AC Electrical Characteristics of Fast1 General I/O 2
1 Fast/slow characteristic is selected per GPIO (where available) by “slew rate” control. See reference manual.
2 Use of GPIO in fast mode with the associated NVCC > 1.95 V can result in excessive overshoot and ringing.
