Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz
[7]
Effective number of bits are obtained via a fast Fourier transform (FFT). The calculation takes into account all harmonics and noise up to
half of the clock frequency (Nyquist frequency). Conversion to Single-to-noise-and-distortion-ratio (SINAD) is given by
SINAD = ENOB
×
6.02 + 1.76 dB; see
Figure 5
.
[8]
Intermodulation measured relative to either tone with analog input frequencies of 20 and 20.1 MHz. The two input signals have the
same amplitude and the total amplitude of both signals provides full-scale to the converter (
6 dB below full-scale for each input signal).
IMD3 is the ratio of the RMS value of either input tone to the RMS value of the worst case third order intermodulation product.

Output data acquisition: the output data is available after the maximum delay of t
d(o)
; see
Figure 3
