General description

The DAC1005D650 is a high-speed 10-bit dual-channel Digital-to-Analog Converter (DAC) with selectable 2×, 4×or 8×interpolating filters optimized for multi-carrier wireless transmitters. Thanks to its digital on-chip modulation, the DAC1005D650 allows the complex I and Q inputs to be converted up from BaseBand (BB) to IF. The mixing frequency is adjusted using a Serial Peripheral Interface (SPI) with a 32-bit Numerically Controlled Oscillator (NCO). The phase is controlled by a 16-bit register. Two modes of operation are available: separate data ports or a single interleaved

high-speed data port. In the Interleaved mode, the input data stream isdemultiplexed into its original I and Q data and then latched.
