Overview: www.ti.com 8 DAC5674 SLWS148A − SEPTEMBER 2003 − REVISED OCTOBER 2005 14ĆBIT, 400 MSPS, 2y/4y INTERPOLATING CommsDAC DIGITALĆTOĆANALOG.

General Description

The DAC5674 is a 14-bit resolution, high-speed, digital-to-analog converter (DAC) with integrated 4× interpolation filter, onboard 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 4× interpolation filter is implemented as a cascade of two 2× interpolation filters, each of which can be configured for either low-pass or high-pass response.
