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 pattern data per pin and can produce formatted outputs and perform comparisons of DUT expected responses. Each channel of the ADATE207 provides 256 selectable waveforms, wherein each waveform consists of up to four possible events. Each event consists of a programmable timing edge and a STIL-compatible (IEEE Standard 1450-1999) set.
