Overview
The AD9164BBCZRL, produced by Analog Devices Inc., is a high-performance, 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS). This component supports update rates up to 6 GSPS and is designed for demanding high-speed radio frequency (RF) applications. The DAC core utilizes a quad-switch architecture combined with a 2× interpolator filter, enabling an effective DAC update rate of up to 12 GSPS in certain modes. The DDS features a bank of 32, 32-bit numerically controlled oscillators (NCOs), each with its own phase accumulator, facilitating phase coherent fast frequency hopping (FFH) and supporting multiple application modes.
