The AD9954YSV is a highly integrated direct digital synthesizer (DDS) integrated circuit (IC) component developed by Analog Devices. This IC is designed to provide a versatile and cost-effective solution for advanced modulation and frequency synthesis applications. It combines a high-speed DAC (digital-to-analog converter) and a dedicated DDS core to achieve excellent frequency resolution and phase noise performance.
The key features of the AD9954YSV include:
1. Wide Frequency Range: This IC supports a frequency range up to 200 MHz for the DDS core. It allows for precise frequency synthesis and modulation across a broad spectrum.
2. High-Speed DAC: The integrated 10-bit DAC enables the generation of fast analog waveforms with a sample rate up to 400 MSPS (million samples per second). It ensures accurate and high-resolution analog output.
3. Multi-channel Operation: The AD9954YSV offers four independent DDS channels, each with its phase accumulator, digital ramp generator, and programmable phase offset. This feature allows simultaneous and independent frequency and phase modulation on multiple channels.
4. Large On-chip Memory: It incorporates a large 12-bit wide RAM (random access memory) enabling a substantial 48K-word capacity. This memory can be used for various purposes such as storing frequency profiles or waveform table-based modulation
