1. All AC specifications tested bydriving ENCODE and ENCODE differentially.
2. Analog input signal power at -1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to toatl noise (first five harmonics
removed).
3. Analog input signal power at -1 dBFS; signal-to-noise and distorsion (SINAD) is the ratio of signal level to toatl noise + harmon-
ics.
4. Analog input signal power at -1 dBFS; worst spur is the ratio of signal level to worst spur, usually limited by harmonics.
5. 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.
6. 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.
7. Both input tones swept from -20 to -95 dBFS; dither power = -32.5 dBm; dither circuit used on input signal two-tone spurious-
free dynamic range (SFDR) is the ratio of converter full scale to worst spur.
8. Guaranteed by design.
