AD9164BBCAZ

AD9164 is a high performance, 16bit digital-to-analogue converter (DAC) and direct digital synthesizer (DDS) that supports update rates to 6GSPS. The DAC core is based on a quad-switch architecture coupled with a 2× interpolator filter that enables an effective DAC update rate of up to 12GSPS in some modes. The high dynamic range and bandwidth makes these DACs ideally suited for the most demanding high speed radio frequency (RF) DAC applications. The DDS consists of a bank of 32, 32bit numerically controlled oscillators (NCOs), each with its own phase accumulator. When combined with a 100 MHz serial peripheral interface (SPI) and fast hop modes, phase coherent fast frequency hopping (FFH) is enabled, with several modes to support multiple applications. Application includes broadband communications systems, DOCSIS 3.1 CMTS/ video on demand (VOD)/edge, quadrature amplitude modulation (EQAM), wireless communications infrastructure, W-CDMA, LTE, LTE-A, point to point.
