Description
General part information
ADC3649 Series
The ADC3648 and ADC3649 (ADC364x) are a 14-bit, 250MSPS and 500MSPS, dual channel analog to digital converter (ADC). The devices are designed for high signal-to-noise ratio (SNR) and deliver a noise spectral density of -158.5dBFS/Hz (500MSPS).
The power efficient ADC architecture consumes 300mW/ch at 500MSPS and provides power scaling with lower sampling rates (250mW/ch at 250MSPS).
The ADC364x includes an optional quad band digital down-converter (DDC) supporting wide band decimation by 2 to narrow band decimation by 32768. The DDC uses a 48-bit NCO which supports phase coherent and phase continuous frequency hopping.
