ZHCSFY7B January 2017 – December 2021 ADS58J64
PRODUCTION DATA
The ADS58J64 is equipped with a complex numerically-controlled oscillator. The oscillator generates a complex exponential sequence: x[n] = ejωn. The frequency (ω) is specified by the 16-bit register setting. The complex exponential sequence is multiplied by the real input from the ADC to mix the desired carrier down to 0 Hz.
The NCO frequency setting is set by the 16-bit register value, NCO_FREQ[n]:
