TRANSITION TIME LOCK LOOP WITH REFERENCE ON REQUEST |
摘要 |
Output driver feedback circuitry limits output slew rates across a wide range of output loads. A transition time lock loop architecture of the feedback circuitry compares a transition time pulse with a reference pulse to adjusts transition time of an output signal for various process-voltage-temperature (PVT) process corners, output voltage domains and output capacitances. Reference pulse generation circuitry provides a reference pulse in phase with the transition time pulse for each rise and fall of the output signal.
