The document introduces the CMOS 300 MSPS Complete DDS AD9852 Rev. E. The product has a 300 MHz internal clock rate and supports various functions such as FSK, BPSK, PSK, chirp, and AM operation. It features dual integrated 12-bit D/A converters and an ultrahigh speed comparator, providing excellent dynamic performance. The product also supports programmable features such as frequency, phase, and amplitude modulation. It has a simplified control interface and multiple data interfaces to choose from. Overall, the product is characterized by high performance and versatility.
The AD9852 is a 300 MSPS CMOS DDS synthesizer that integrates dual 12‑bit DACs, a high‑speed comparator, and programmable reference‑clock multipliers. It offers 48‑bit frequency resolution, programmable amplitude and phase control, and supports FSK, BPSK, chirp, and AM modulation modes. The device can generate output frequencies up to 150 MHz and operates over an industrial temperature range.
The document includes detailed specifications, absolute maximum ratings, thermal resistance data, pin‑out tables, timing characteristics for parallel and serial interfaces, and ordering information for the available 80‑lead TQFP packages. It also provides application notes, mode‑of‑operation descriptions, and guidelines for evaluation board use.
