Abstract: The proposed invention is about an improved method for serial-in and serial-out transceiver applications. The proposed system includes a dual loop phase locked loop (PLL) architecture having a PLL and a phase rotator (PR)-based delay locked loop (DLL). An advantage of this architecture is that a single PLL offers decoupled bandwidths; a wide jitter-tolerance (JTOL) bandwidth for receiving data and a narrow jitter transfer (JTRAN) bandwidth for the data transmission. Thus, the amount of jitter at the output can be substantially reduced relative to the input while offering sufficient jitter tracking bandwidth. Also, this architecture is suitable for low-power applications since a phase shifter in the data path, which is one of the most power-hungry blocks in conventional DPLL designs, is not required.

Abstract translation: 所提出的发明是关于串行和串行收发器应用的改进方法。 所提出的系统包括具有PLL和基于相位旋转器（PR）的延迟锁定环（DLL）的双环路锁相环（PLL）架构。 该架构的优点是单个PLL提供去耦带宽; 用于接收数据的宽抖动容限（JTOL）带宽和用于数据传输的窄抖动传输（JTRAN）带宽。 因此，在提供足够的抖动跟踪带宽的同时，输出端的抖动量可以相对于输入显着减小。 此外，该架构适用于低功耗应用，因为数据路径中的移相器是传统DPLL设计中功耗最大的块之一。
