A 12‐Gb/s serial link transceiver using dual‐mode pulse amplitude modulation scheme in a 0.18‐μm CMOS process

Abstract

SummaryA 12‐Gb/s 0.18‐μm complementary metal oxide semiconductor (CMOS) serial link transceiver with embedded clock signal in data stream using dual‐mode pulse amplitude modulation is presented. The 6‐bit data and the clock signal are both transferred through the same transmission channel. In the proposed modulation technique, the clock signal is easily recovered using a conventional phase‐locked loop without any complex encoders in the transmitter circuit. The transmitter includes multiplexers, an output driver, and pre‐emphasis circuitry with 127‐mW power consumption. The receiver is composed of a phase‐locked loop for clock recovery and demodulator blocks for data recovery, and it dissipates 45 mW of power.
