ABSTRACT:
A V.35 compliant driver is disclosed. The driver has three operational modes: OFF, low power (approximately 1/3 full power), and full power. The driver is placed in an appropriate mode based on conditions sensed at driver outputs. More particularly, the driver turns OFF upon sensing a short circuit condition, and reverts back to a normal operating condition following cessation of the short circuit condition by transitioning through a low power mode. Innovative approaches for satisfying V.35 source impedance measurement requirements and driver termination are also disclosed. All of the components associated with the driver reside on a single integrated circuit.
