Abstract
Systems and methods are provided for jitter improvement in serializer-deserializer (SerDes) transmitters. One or more adjustments may be applied in SerDes transmitter circuitry to reduce jitter in a serial output of the SerDes transmitter circuitry, which may occur as a result of processing of input data. Applying the one or more adjustments may comprise use of dummy data. The dummy data may be configured to generate corresponding dummy current pulses which may in turn be used in controlling supply variations occurring during processing of the input data and/or generation of the serial output. The dummy data may be configured to generate the dummy current pulses such that they are applied along with current pulses corresponding to the input data. The dummy data may be adaptively set or adjusted based on the input data. The use of the dummy data may be selectively turned on or off.
