Abstract
A redundancy switch includes at least three data ports and a control input. Each data port includes a data input and a data output. The redundancy switch operates in one of at least three states. In a first state, a first data port is communicatively coupled with a second data port. In a second state, the first data port is communicatively coupled with a third data port. In a third state, the second data port is communicatively coupled with the third data port. The state of the redundancy switch can be controlled based on a signal received at the control input. The redundancy switch can further include transconductance switching elements that convert a voltage input to a current output.
