Intelligent robot control systems based on multiprocessors, sensors and actuators, require a flexible network for communicating various types of data (e.g. sensor data, interrupt signals). Furthermore, serial data transfer implemented with a few wire lines is also required. For solving the problems, a CDMA serial communication interface utilizing a new two-step synchronization technique is proposed. The receiver chip fabricated in a 0.25μm digital CMOS technology achieves a 2Gb/s data-transfer rate and synchronization of 7 multiplex communications.
