AFE7070 Overview
Description
The AFE7070 is a dual 14-bit 65-MSPS digital-toanalog converter (DAC) with integrated, programmable fourth-order baseband filter and analog quadrature modulator. The AFE7070 includes additional digital signal-processing features such as a numerically controlled oscillator for frequency generation/translation, and a quadrature modulator correction circuit, providing LO and sideband suppression capability.
