Abstract
A reconfigurable transceiver is claimed for a wide range of I/O systems. The reconfigurable transmitter of the reconfigurable transceiver is capable of transmitting multi-level signals in single-ended and differential modes by current and voltage mode signaling. The signal for transmission can be pre-emphasized for all transmitting modes. The reconfigurable transceiver can dynamically scale bandwidth and power consumption based on performance metrics.
Claims20
A reconfigurable transmitter comprising:
- at least two source transistors operable to provide current source and linear resistance;
- a switch, coupled with the at least two source transistors, to provide a virtual common connection between terminals of the at least two source transistors;
- at least two input transistors, coupled with each of the at least two source transistors, to receive signals for transmission;
- at least two controllable terminators, coupled with the at least two input transistors, to provide an impedance termination;
- and
- output probes coupled with the input transistors and the at least two controllable terminators to output the received signals for transmission as a multi-mode signal, wherein the at least two input transistors are operable to apply tunable pre-emphasis on the received signals for transmission.
