AD9777BSV Products

The AD9777BSV is the 16-bit member of a new pin-compatible family of high-speed dual Interpolating TxDAC+® converters with a maximum input data rate of 160 MSPS (no interpolation) and maximum DAC update rate of 400 MSPS (8x interpolation). They feature a selectable interpolation rate (2x/4x/8x) and a complex modulator that can mix at Fs/2, Fs/4 or Fs/8. All configuration is accomplished through an easy to use 3- or 4-wire SPI interface.

When used with an external quadrature modulator (such as the AD8345/AD8346/AD8349) the AD977X can be used implement a more traditional baseband I/Q architecture or an image reject upconversion architecture by using its internal complex (I&Q) mixer. The latter architecture may be well suited for those applications demanding high modulation accuracy (i.e. 64 QAM) that digital modulation inherently provides. This offers the added benefit of suppressing the image inherent in an analog mixing operation, consequently reducing the number of filtering stages, and therefore the cost of the hardware required to achieve 3G and broadband spectral emission specifications. User-accessible Gain and Offset correction is accessed through the SPI port and improves sideband suppression and LO feedthrough, respectively. A direct IF mode allows synthesis of intermediate frequencies (IFs) above 70 MHz.
