Paper Abstract

A mixed analog/digital integrated circuit which performs the post optical signal processing functions for an acousto-optic channelizer system is presented. The signal analysis and additional specialized functions on this circuit provide a complete solution to the processing needs of highly compact channelizer systems. Functionality of the 27-channel postoptical processor is achieved with a single design pass and wafer run. Wafers probed with automatic test equipment, based on a several-thousand vector long functional probe program, yielded an average of 44 percent which is considered to be a good yield for a die of this complexity and size. It is concluded that the integration of all necessary functions makes it possible to reduce channelizer system weight, volume, and power consumption by several orders of magnitude.
