Dual 16-Bit DAC, up to 1.25Gsps; 2x, 4x and 8x Interpolating

The DAC1627D1G25 is a 16-bit dual-channel digital-to-analog converter (DAC) with selectable 2x, 4x, and 8x interpolation filters optimized for multi-carrier broadband wireless transmitters at sample rates up to 1.25Gsps. Supplied from 3.3V and 1.8V power sources, it integrates a differential scalable output current up to 34mA. The mixer frequency is set by a high-resolution 40-bit numerically controlled oscillator (NCO). High-resolution internal gain, phase, and offset control provide outstanding image and LO rejection at the system analog modulator output. An inverse (sin x)/x function ensures controlled flatness at the DAC output. The LVDS DDR receiver interface allows a high data bandwidth (312.5MS/sec) at the input.
