A novel data processing circuit in high-speed serial communication

A novel data processing circuit in high-speed serial communication has been demonstrated in this work. The circuit, including a serializer and a frequency divider, was developed to convert the transmission signals into the desired format. The chip design is based on TSMC 0.25/spl mu/m mixed signal model, and semi-custom design methodology is used. Pre- and post-layout simulation results indicated that the speed of circuit has reached 480MHz. Moreover, the data are processed properly in agreement with USB2.0 specification.
