Abstract:
1. An arrangement for dynamically clamping overshoot in a received signal on a signal line while not clamping the received signal at times when the overshoot is not likely encountered, the arrangement comprising: an activation element configured to assert a Clamp Enable signal in response to a transition of the received signal; a deactivation element configured to assert a Clamp Disable signal after the Clamp Enable signal is asserted; and a clamping portion configured to clamp the received signal beginning with the assertion of the Clamp Enable signal and ending with the assertion of the Clamp Disable signal wherein: the activation element is configured to assert the Clamp Enable signal in response to the transition of the received signal that occurs during a period in which a Driver Disable signal is asserted.
