AD9915BCPZ

The AD9915BCPZ is a high-performance direct digital synthesizer (DDS) from Analog Devices that integrates a 12-bit digital-to-analog converter (DAC) on-chip. It operates at a master clock frequency of 2.5 GSPS, enabling agile frequency synthesis with fine resolution. The device provides a frequency tuning resolution of 135 pHz, 16-bit phase tuning resolution, and 12-bit amplitude scaling. Typical phase noise is -128 dBc/Hz at a 1 kHz offset from a 978 MHz carrier, and wideband SFDR is better than -57 dBc.

The DDS supports programmable modulus for arbitrary frequency generation and offers automatic linear and nonlinear frequency sweeping. It includes eight frequency/phase offset profiles for fast switching. Data interface options include both parallel (32-bit) and serial control. An integrated PLL REF CLK multiplier allows flexible reference clock multiplication. The device also features phase and amplitude modulation capability and multichip synchronization for arrayed systems.

The AD9915BCPZ is available in an 88-lead LFCSP package (12x12 mm) with exposed pad for thermal management. It operates from dual power supplies of 1.8V and 3.3V, and supports software and hardware power-down modes. The operating temperature range is -40°C to +85°C. The part is surface mount and RoHS3 compliant (unverified).
