AD9777BSVZ

AD97771 is the 16bit member of the AD977x pin compatible, high performance, programmable 2×/4×/8× interpolating TxDAC+. The AD977x family features a serial port interface (SPI) that provides a high level of programmability, thus allowing for enhanced system level options. This option includes selectable 2×/4×/8× interpolation filters; fS/2, fS/4, or fS/8 digital quadrature modulation with image rejection; a direct IF mode; programmable channel gain and offset control; programmable internal clock divider; straight binary or twos complement data interface; and a single port or dual-port data interface. Application includes communications, analogue quadrature modulation architecture, 3G, multicarrier GSM, TDMA, CDMA systems, broadband wireless, point-to-point microwave radios, instrumentation/ATE.
