The ADC34RF55 is a single core 14-bit, 3-GSPS, quad channel analog to digital converters (ADC) that support RF sampling with input frequencies up to 3 GHz. The design maximizes signal-to-noise ratio (SNR), and delivers a noise spectral density of -156 dBFS/Hz. Using additional internal ADCs along with on-chip signal averaging, the noise density improves to -158 dBFS/Hz.

Each ADC channel can be connected to a dual-band digital down-converter (DDC) using a 48-bit NCO which supports phase coherent frequency hopping. Using the GPIO pins for NCO frequency control, frequency hopping can be achieved in less than 1 µs.

The devices supports the JESD204B serial data interface with subclass 1 deterministic latency using data rates up to 13Gbps. There are only 2 serdes lanes per ADC channel. Therefore, in bypass mode, the maximum output data rate supported is 1.5GSPS. When using faster ADC sampling rates on chip, decimation is required.

The power efficient ADC architecture consumes 1.2W/ch and provides power scaling with lower sampling rates.
