A ll AC specifications tested by driving ENCODE and ENCODE differentially.
Analog input signal power at -1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to total noise (first five harmonics removed).
Analog input signal power at -1 dBFS; signal-to-noise and distorsion (SINAD) is the ratio of signal level to total noise + harmonics.
Analog input signal power at -1 dBFS; worst spur is the ratio of signal level to worst spur, usually limted by harmonics.
Analog input signal power swept from-20 dBFS to -95 dBFS; dither power = -32.5 dBm dither circuit used on input signal SFDR is ratio of converter full scale to worst spur.
Tones at -7dBFS (F1 = 15.3 MHz, F2 = 19.5 MHz); two tone intermodualtion distortion (IMD) rejection is ratio or either tone to worst third order intermod product.
Both input tones swept from-20 to -95 dBFS; dither power = -32.5 dBm dither circuit used on input signal two-tone spurious-free dynamc range (SFDR) is the ratio of converter full
scale to worst spur.
Guaranteed by design.
