A pipelined serial data receiver with oversampling techniques for high-speed data communications

In this paper, we propose a novel oversampling receiver to achieve NRZI (Non-Return-to-Zero-Inverted) data recovery for serial link communications. Adopting feed-forward not conventional PLL (Phase-Locked Loop) feed-back operation is quite suitable for high-bandwidth applications. The employment of byte-level pipelined architecture greatly reduces the complexity of the system clock configuration. Moreover, the characteristic of high data deviation tolerance was indicated from the experimental results.
