Overview
DAC1405D650 Dual 14-bit DAC, up to 650 Msps; 2, 4 and 8 interpolating Rev.
05 — 2 July 2012 Product data sheet 1.
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 regulator to adjust...
