The AD9851BRSZ is an integrated circuit (IC) component developed by Analog Devices. It is a direct digital synthesizer (DDS) that offers a wide range of functionalities and features, making it ideal for various applications. Here is an overview and key features of the AD9851BRSZ:
1. Frequency Generation: The AD9851BRSZ is capable of generating precise and stable frequencies in the range of 0 Hz to 125 MHz. It employs a 48-bit phase accumulator that enables frequency resolution as fine as 0.0291 Hz.
2. Digital-to-Analog Converter (DAC): This IC includes a 10-bit DAC that provides high-resolution digital-to-analog conversion. The DAC is responsible for converting the digital signals generated by the DDS into analog output signals.
3. Frequency Tuning Speed: The AD9851BRSZ offers fast frequency tuning capabilities, enabling it to change frequencies with minimal delay. It features a 32-bit frequency tuning word (FTW) that allows rapid frequency adjustments.
4. Programmable Phase Offset: With this IC, users can easily program phase offsets between 0 and 360 degrees. This feature proves valuable in applications requiring precise phase control.
5. On-Chip Reference Clock: The AD9851BRSZ incorporates a high-speed on-chip reference clock oscillator, eliminating the need for an external clock source. This simplifies the design process and reduces system costs
