General description The DAC1405D650 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 wireless transmitters.
Thanks to its digital on-chip modulation, the DAC1405D650 allows the complex I and Q inputs to be converted up from baseband to IF.
The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit Numerically Controlled Oscillator (NCO) and 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 DAC1405D650 also includes a 2×, 4× and 8× clock multiplier which provides the appropriate internal clocks and an internal reg...
