Description

The ADC3548 and ADC3549 (ADC354x) is a 14-bit, 250 and 500MSPS, single channel analog to digital converter (ADC). The device is designed for high signal-to-noise ratio (SNR) and delivers a noise spectral density as low as -158.5dBFS/Hz.

The power efficient ADC architecture consumes 435mW at 500MSPS and provides power scaling with lower sampling rates (369mW at 250MSPS).

The ADC354x includes a 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.

The ADC354x is outfitted with a flexible LVDS interface. In decimation bypass mode, the device uses a 14-bit wide parallel SDR or DDR LVDS interface. When using decimation, the output data is transmitted using a serial LVDS interface reducing the number of lanes needed as decimation increases. For high decimation rates, the output resolution can be increased to 32-bit.
