AD9914BCPZ Analog Devices Datasheet

AD9914bcpz Pinout Equivalent Circuit

AD9914bcpz is a high-performance direct digital synthesizer produced by Analog Devices. It adopts advanced digital signal synthesis technology and is equipped with a 3.5-GSPS high-speed clock and a 12 bit high-precision DAC, which can achieve 16 bit phase fine-tuning and 12 bit amplitude control. It has programmable analog-to-digital function and automatic linear and nonlinear frequency scanning function. At 1396 MHz with a 1 kHz offset, ultra-low phase noise of -128 dBc/Hz can be achieved, while maintaining broadband SFDR below -50 dBc. Adopting 1.8V/3.3V dual power supply and providing software and hardware dual shutdown function; The built-in PLL REF CLK multiplier further enhances clock stability.
AD9914bcpz adopts LFCSP-88 (12×12) package, and the specific pin definitions are as follows:

Alternative chip selection

In hardware system design, when searching for alternative devices for AD9914BCPZ due to supply, cost, or special application requirements, the key parameters to consider are as follows: the first alternative chip needs to cover the frequency band required by the target system (if the frequency band can be reduced, lower level alternatives can be selected); The second requirement is to have high resolution, low phase noise, and multiple modulation functions similar to AD9914; The third is to ensure that the substitute products are compatible with SPI communication interfaces and packaging forms, so that there is no need to redesign the PCB and the product can be modified faster.
