NOTES
1All ac specifications tested by driving ENCODE and ENCODE differentially, with the analog input applied to AINX1 and AINX2 tied to ground.
2SFDR enabled (SFDR = 1) for DNL and INL specifications.
3Gain error measured at 10.3 MHz.
4Input VSWR, see TPC 14.
5See Figure 1, Timing Diagram.
6tV and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital outputs swing. The digital output load during
test is not to exceed an ac load of 10 pF or a dc current of ± 40 A.
7Supply voltages should remain stable within ± 5% for normal operation.
8Power dissipation measures with encode at rated speed.
9Analog input signal power at –1 dBFS; signal-to-noise (SNR) is the ratio of signal level to total noise (first six harmonics removed). ENCODE = 125 MSPS,
SFDR mode = 1. SNR is reported in dBFS, related back to converter full-scale.
10Analog input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. ENCODE = 125 MSPS.
SINAD is reported in dBFS, related back to converter full-scale.
11Analog input signal equals –1 dBFS; SFDR is ratio of converter full-scale to worst spur.
12Both input tones at –7 dBFS; two-tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third order intermod product.
13Channel-to-channel isolation tested with A channel/50 Ω terminated (AIN A2) grounded and a full-scale signal applied to B channel (AIN B2).
Specifications subject to change without notice.
