Note 1: Dynamic performance is based on a 32,768-point data record with a sampling frequency of f
SAMPLE
= 65.0117120MHz, an
input frequency of f
IN
= f
SAMPLE
x (7561/32768) = 15.001024MHz, and a frequency bin size of 1984Hz. Close-in (f
IN
±23.8kHz) and low-frequency (DC to 47.6kHz) bins are excluded from the spectrum analysis.
Note 2: Apply the same voltage levels to DV
CC
and DRV
CC
.
Note 3: Guaranteed by design and characterization.
