AD9854AST General Description

The AD9854AST from Analog Devices is a cutting-edge Direct Digital Synthesis (DDS) chip that boasts top-notch performance. With a 300MHz internal clock frequency that can be boosted up to 1.2GHz through an internal modulator, this chip is a powerhouse for generating precise and stable frequency output signals across a wide range from DC to 300MHz. Its 10-bit digital-to-analog converter (DAC) ensures accuracy in signal generation, making it a go-to choice for communication, radar, and test and measurement applications. Its exceptional frequency resolution, phase noise, and spurious performance further solidify its place as a versatile and reliable tool in various industries
