ABSTRACT:
A hot-swappable, point-to-point connection between a high speed transmitter on a transmitter card and a high speed receiver on a receiver card is provided. The transmitter card and the receiver card can be inserted into a backplane, the backplane forming the connection between the transmitter and the receiver. The system includes a power indicator on the transmitter card and the receiver card, with each power indicator asserting a power signal to respective switch control inputs on the transmitter and receiver cards when the respective cards are inserted into the backplane. The assertion or unassertion of a power signal to the control inputs allows for the disabling of the receiver when the transmitter is not connected to the backplane and the disabling of the transmitter when the receiver is not connected to the backplane, thereby preventing transmitter output EMI and ringing and receiver input oscillation.
