GENERAL DESCRIPTION The ADATE207 is a timing generator and formatter for automatic test equipment (ATE) equipment. The ADATE207 provides four independent channels with a 100 MHz base vector rate of timing and formatting for ATE digital pins. It interfaces between the pattern memory,and the driver, comparator, and load (DCL) chips for complete digital pins. The ADATE207 accepts up to eight bits of...
