Description
General part information
ADC34RF55 Series
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.
