The AD9773 is the 12 bit member of the AD977x family of pin-compatible, high performance, programmable 2*/4*/8* interpolating TxDAC+s. The AD977x family features a serial port interface (SPI) providing a high level of programmability thus allowing for enhanced system level options. These options include: 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 two's complement data interface; and a single port or dual port data interface.
