The DAC5674 is a 14-bit resolution high-speed digital-to-analog converter (DAC) with integrated 4x-interpolation filter, on-board clock multiplier, and on-chip voltage reference. The device has been designed for high-speed digital data transmission in wired and wireless communication systems, high-frequency direct-digital synthesis (DDS) and waveform reconstruction in test and measurement applications. The 4x-interpolation filter is implemented as a cascade of two 2x-interpolation filters, each of which can be configured for either low-pass or high-pass response. This enables the user to select one of the higher order images present at multiples of the input data rate clock while maintaining a low date input rate. The resulting high IF output frequency allows the user to omit the conventional first mixer in heterodyne transmitter architectures and directly up-convert to RF using only one mixer, thereby reducing system complexity and costs. |
