Abstract: Systems and methods are provided for handling jitter improvement in transmitters. During processing of input data for serial transmission, it may be determined if jitter may occur, and when jitter occurs one or more adjustments may be determined, based on dummy data, to reduce jitter in an output corresponding to the input data. The one or more adjustments may then be applied during processing of the input data, to reduce jitter in a serial output corresponding to the input data. The dummy data may be generated based on the input data. The dummy data may be configured such that it may generate corresponding dummy current pulses which may be used in controlling supply variations during generation of the serial output. The use of the dummy data may be selectively turned on or off.

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.

Abstract translation: 提供了串行器 - 解串器（SerDes）发射机的抖动改进的系统和方法。 可以在SerDes发射机电路中应用一个或多个调整，以减少由于输入数据的处理而发生的SerDes发射机电路的串行输出中的抖动。 应用一个或多个调整可以包括使用虚拟数据。 虚拟数据可以被配置为产生相应的虚拟电流脉冲，其可以用于控制在处理输入数据期间发生的电源变化和/或产生串行输出。 伪数据可以被配置为产生虚拟电流脉冲，使得它们与对应于输入数据的电流脉冲一起被施加。 可以基于输入数据自适应地设置或调整虚拟数据。 可以选择性地打开或关闭虚拟数据的使用。
