Abstract :
A 32-b GaAs asynchronous serial data transmitter and receiver chip set has been developed for parallel data processing systems. The chip set has asynchronous parallel data inputs, a framing circuit, and a parity checker for reliable data transmission and easy data handling. The operating speed of the chip set is up to 500 Mb/s. The transmitter and receiver chips contain 1300 gates and 1400 gates, respectively. Power dissipations of both chips were as low as 1 W. Each chip is 4.4 mm*2.8 mm. The chip set was fabricated using 1- mu m W-Al gate self-aligned MESFETs with a high yield.<>
