Product data sheet
1. General description
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. 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.
