AD9851BRSZRL

The AD9851BRSZRL is a direct digital synthesizer (DDS) from Analog Devices, designed for high-speed frequency generation with precision. It features a 32-bit frequency tuning word, enabling fine resolution, and supports clock rates up to 180 MHz, generating frequencies up to 70 MHz.
Key features include:
- 10-bit DAC for analog output.
- Serial or parallel interface for easy microcontroller integration.
- Phase modulation capability.
- Low power consumption (~380 mW at 180 MHz).
Applications include signal generators, communications systems, and test equipment. The BRSZRL suffix denotes a RoHS-compliant, tape-and-reel packaged version.
Its compact design and high performance make it ideal for programmable frequency synthesis in embedded systems.
