The innovative design of the internal T/H assures an exceptionally wide 1.2GHz input bandwidth and aperture delay uncertainty of less than 2ps, resulting in a high 7.0 effective bits at the Nyquist frequency. Special comparator output design and decoding circuitry reduce out-of-sequence code errors. The probability of erroneous codes due to metastable states is reduced to less than 1 error per 1015 clock cycles. And, unlike other ADCs that can have errors resulting in false fullscale or zero-scale outputs, the MAX101 keeps the error magnitude to less than 1LSB.
