The AD9066 is a dual 6-bit ADC that has been optimized for low-cost in-phase and quadrature (I and Q) demodulators. Primary applications include digital direct broadcast satellite applications where broadband quadrature phase shift keying (QPSK) modulation is used. In these receivers the recovered signal is separated into I and Q vector ponents and digitized. To reduce total system cost and power...
