  • Reduction in power supply induced jitter on a SerDes transmitter
    Patent number: 8964880
    Abstract: In an embodiment of the invention, a frequency divider in a phase-locked loop (PLL) circuit is provided power from the power supply that provides power to a transmission circuit. The PLL is configured to receive a first direct current (DC) reference voltage, a second DC voltage and a reference clock signal. The PLL is configured to generate a transmission clock signal. A transmission circuit is configured to receive the transmission clock signal, the second DC voltage and a data bus where the data bus includes a plurality of data bits in parallel. The transmission circuit transmits data serially.
