Abstract
A serial transmitter that outputs one symbol every unit interval (UI) from a data source is presented. The serial transmitter includes a serial output port that outputs one symbol every unit interval (UI) from a data source. The serial transmitter also includes a plurality of driver segments that jointly drive the serial output port. Each driver segment is configured to use one of N phases of a sampling clock to serialize and transmit data from the data source. Different sets of the driver segments are configured to use different phases of the sampling clock for serializing and transmitting data, the sampling clock being a half-rate clock having a period of two UI.
Claims15
An integrated circuit (IC) comprising:
- a serial output port that outputs one symbol every unit interval (UI);
- a data source;
- and
- a plurality of driver segments that jointly drive the serial output port,
- wherein each driver segment is configured to select, by a phase selector, one of N phases of a sampling clock for serializing and transmitting data from the data source, and
- wherein different sets of the driver segments are configured to use different phases of the sampling clock for serializing and transmitting data, the sampling clock being a half-rate clock having a period of two UI.
A computer-implemented method comprising:
- receiving configuration data for configuring a plurality of driver segments of a serial transmitter to serialize and transmit data from a data source, the plurality of driver segments jointly driving a serial output port of the serial transmitter that outputs one symbol every unit interval (UI);
- configuring a first set of driver segment, by a phase selector, based on the configuration data, to select a first phase of a sampling clock for serializing data from the data source;
- and
- configuring a second set of driver segment, by a phase selector, based on the configuration data, to select a second phase of a sampling clock for serializing data from the data source,
- wherein the sampling clock is a half-rate clock having a period of two UI.
