This section outlines the Clock Amplifier Module (CAMP) specific electrical characteristics.
shows clock amplifier electrical characteristics.
Freescale Semiconductor
PA1
Use of DDR Drive can result in excessive overshoot and ringing.
Fast/slow characteristic is selected per GPIO (where available) by “slew rate” control. See reference manual.
Fast/slow characteristic is selected per GPIO (where available) by “slew rate” control. See reference manual.
Use of GPIO in fast mode with the associated NVCC > 1.95 V can result in excessive overshoot and ringing.
