DAC1408D650 - IDT

DAC1408D650 Dual 14-bit DAC

The DAC1408D650 is a high-speed 14-bit dual channel Digital-to-Analog Converter (DAC) with selectable 2, 4 or 8 interpolating filters optimized for multi-carrier WCDMA transmitters. Because of its digital on-chip modulation, the DAC1408D650 allows the complex pattern provided through lane 0, lane 1, lane 2 and lane 3, to be converted from baseband to IF. .
