Overview
The AD9164BBCAZRL, produced by Analog Devices Inc., is a high-performance 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS). This component is designed to support update rates up to 6 GSPS and features a quad-switch architecture coupled with a 2× interpolator filter, enabling an effective DAC update rate of up to 12 GSPS in certain modes. The AD9164 is ideal for demanding high-speed radio frequency (RF) DAC applications due to its high dynamic range and bandwidth.
The DDS component includes a bank of 32, 32-bit numerically controlled oscillators (NCOs), each with its own phase accumulator, enabling phase coherent fast frequency hopping (FFH) with several modes to support multiple applications. The device also features a 100 MHz serial peripheral interface (SPI) for configuration and status monitoring.
