    摘要: The present disclosure provides techniques for recovering source stream clock data at the sink in a high definition multimedia digital content transport system. The disclosure includes a fractional-N Phase-Locked Loop (PLL) based clock generator, a programmable Sigma-Delta Modulator (SDM), and a clock data calibrator to fully recover the original source stream clock data. The fractional-N PLL provides flexible source stream clock recovery. When there is a frequency deviation between the original clock and the regenerated clock, the clock data calibrator control circuit adjusts the clock data, preventing any stream data buffer overflow or underflow problems. The disclosed techniques are compatible with the sink devices based on the standards of DisplayPort and HDMI.

    摘要: The methods and systems presented herein provide an improved means of correcting the variation of Voltage Output Differential (VOD) in differential drivers. In some embodiments, a high-precision reference voltage is generated not only based on a desired VOD, but also by monitoring the Voltage Common Mode (VCM) in a differential driver. In some embodiments, the VOD is then compared with the high-precision reference voltage to correct the output current. The result is a low-variation output voltage.
