ADATE207时序发生器和格式化设备程序
分享资料个
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. Each timing edge generator can produce an edge with a span of four periods with a 39.06 ps edge placement resolution. The delay generators use a reference master clock of 100 MHz and provide programmable delays based upon counts of the clock and a compensated CMOS analog timing vernier. The programmable delay generators can be additionally delayed by a global 8-bit input value that is shared across all edges. The format and compare logic support ×2 pin multiplexing to allow the trading of pin count for speed. Each channel provides a 4-bit DUT output capture supporting mixed signal receive memory applications. The fail detection logic includes a 32-bit fail accumulation register per channel. An external TMU is supported with three 8-to-1 multiplexers. This allows the dual comparator outputs of any pin to be multiplexed to any of the three outputs： arm， start， or stop signals.
