Analog Devices AD9957 Data Sheet Rev C
The AD9957 is a 1 GSPS quadrature digital upconverter with an 18‑bit I/Q data path and a 14‑bit DAC, designed for communications systems where size, power consumption, and performance are critical. It integrates a high‑speed DDS, a 14‑bit DAC, clock multiplier circuitry, digital filters, and other DSP functions onto a single chip.\n\nThe data sheet includes sections on features, applications, functional block diagram, electrical specifications, absolute maximum ratings, pin configuration, timing characteristics, and various operation modes such as quadrature modulation, BlackFin interface, interpolating DAC, and single‑tone mode. Detailed electrical specs, power consumption figures, and layout dimensions are also provided.
