1
All ac specifications tested by driving ENCODE and
ENCODE
differentially; see the Encoding the AD9042 section for details.
2
C1 (Pin 10 on AD9042ASTZ only) tied to GND through a 0.01 μF capacitor.
3
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).
4
Analog input signal power at −1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics.
5
Analog input signal power at −1 dBFS; worst spur is the ratio of the signal level to worst spur, usually limited by harmonics.
6
Analog input signal power swept from −20 dBFS to –95 dBFS; dither power = −32.5 dBm; dither circuit used on input signal (see the Overcoming Static Nonlinearities
with Dither section); SFDR is the ratio of converter full scale to worst spur.
7
Tones at −7 dBFS (f1 = 15.3 MHz, f2 = 19.5 MHz); two-tone intermodulation distortion (IMD) rejection is ratio of either tone to worst-third order intermodulation
product.
8
Both input tones swept from −20 dBFS to −95 dBFS; dither power = −32.5 dBm; dither circuit used on input signal (see the Overcoming Static Nonlinearities with
Dither section); two-tone spurious-free dynamic range (SFDR) is the ratio of converter full scale to worst spur.
