General description
The DAC1005D650 is a high-speed 10-bit dual-channel Digital-to-Analog Converter (DAC) with selectable 2x, 4x or 8x 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 is demultiplexed into its original I and Q data and then latched.
The DAC1005D650 also includes a 2x, 4x and 8x clock multiplier which provides the appropriate internal clocks and an internal regulator to adjust the output full-scale current.
