Конкретно надо идти сюда

Analog-to-Digital Converter (ADC) and
Digital-to-Analog Converter (DAC) integrated
circuits, as follows:
a.5.a. ADCs having any of the following:
a.5.a.1. A resolution of 8 bit or more,
but less than 10 bit, with an output rate greater
than 1 billion words per second;
a.5.a.2. A resolution of 10 bit or more, but
less than 12 bit, with an output rate greater than
300 million words per second;
a.5.a.3. A resolution of 12 bit with an output
rate greater than 200 million words per second;
a.5.a.4. A resolution of more than 12 bit but
equal to or less than 14 bit with an output rate
greater than 125 million words per second; or
a.5.a.5. A resolution of more than 14 bit with
an output rate greater than 20 million words per
second;
a.5.b. Digital-to-Analog Converters (DAC)
having any of the following:
a.5.b.1. A resolution of 10 bit or more with
an ‘adjusted update rate’ of greater than 3,500
MSPS; or
a.5.b.2. A resolution of 12-bit or more with
an ‘adjusted update rate’ of greater than 1,250
MSPS and having any of the following:
a.5.b.2.a. A settling time less than 9 ns to
0.024 % of full scale from a full scale step; or
a.5.b.2.b. A ‘Spurious Free Dynamic
Range’ (SFDR) greater than 68 dBc (carrier)
when synthesizing a full scale analog signal of
100 MHz or the highest full scale analog signal
frequency specified below 100 MHz.
