Abstract
A multi-mode transmitter within an integrated circuit device. The multi-mode transmitter transmits a first data sequence in a baseband signal when a first transmission mode is enabled, and transmits the first data sequence in a multi-band signal when a second transmission mode is enabled.
Claims21
An integrated circuit device comprising:
- an output node including a pad for coupling to a wired transmission line;
- a plurality of equalizer circuits including coefficient storage circuits for storing selected tap coefficients;
- and
- wireline transmission circuitry coupled to the output node and to output via the output node for wireline transmission along the wired transmission line either a baseband signal or a multi-band signal based on the selected tap coefficients.
A method comprising:
- equalizing in a plurality of equalizers including coefficient storage for storing selected tap coefficients;
- transmitting a first data sequence in a baseband signal along a wired transmission line when a first transmission mode is enabled based on the selected tap coefficients;
- and
- transmitting the first data sequence in a multi-band signal along the wired transmission line when a second transmission mode is enabled based on the selected tap coefficients.
An integrated circuit device comprising:
- means for equalizing with a plurality of equalizers including coefficient storage for storing selected tap coefficients;
- means for wireline transmitting a first data sequence in a baseband signal when a first transmission mode is enabled based on the selected tap coefficients;
- and
- means for wireline transmitting the first data sequence in a multi-band signal when a second transmission mode is enabled based on the selected tap coefficients.
A manufacture comprising one or more non-transitory computer-readable media, the computer-readable media having information embodied therein that describes a physical implementation of an integrated circuit device, the information including descriptions of:
- a plurality of equalizer circuits including coefficient storage circuits for storing selected tap coefficients;
- and
- a multi-band transmitter,
- a baseband transmitter;
- and
- a multiplexer having inputs coupled to respective outputs of the multi-band transmitter and baseband transmitter, the multiplexer having an output selected based on the selected tap coefficients coupled to an output node of an integrated circuit device, the output node including a pad for coupling to a wired transmission line.
