Each ADC operates at up to a 250 MSPS conversion rate with outstanding dynamic performance. The AD9286 takes a single sample clock and, with an on-chip clock divider, time interleaves the two ADC cores (each running at one-half the clock frequency) to achieve the rated 500 MSPS. By using the SPI, the user can accurately adjust the timing of the sampling edge per ADC to minimize the image spur energy. The ADC requires a single 1.8...
