The Mystery is a highly integrated System-on-a-Chip (SoC) pin electronics solution that incorporates every analog function, along with digital support circuitry required to create 8 independent pin channels for Automated Test Equipment. Each channel is configured via a 50MHz SPI interface, and all real time data is programmed and read back through high speed FLEX I/O pins that can be configured to interface directly to other devices using multiple single-ended and differential logic families.
