ECHO CANCELLATION FOR HIGH SPEED FULL DUPLEX DATA TRANSMISSIONS |
摘要 |
Systems, devices and methods for analog echo cancellation for high speed full duplex data transmissions, which include a first set of differential nodes to receive reception data and transmission data, a second set of differential nodes to receive the transmission data, and a subtraction circuit to receive data from the first set of differential nodes and data from the second set of differential nodes. The subtraction circuit includes a plurality of capacitors to receive data from each of the first and second sets differential nodes, and a termination circuit for providing DC termination voltage to subtract the data of the second set of differential nodes from the data of the first set of differential nodes to eliminate echo from the reception data received at the first set differential nodes. |
