adc32rf80irmpt
the adc32rf45 device is a 14-bit, 3.0-gsps, dual-channel, analog-to-digital converter (adc) that supports rf sampling with input frequencies up to 4 ghz and beyond. designed for high signal-to-noise ratio (snr), the adc32rf45 device delivers a noise spectral density of –155 dbfs/hz as well as dynamic range and channel isolation over a large input frequency range. the buffered analog input with on-chip termination provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy.
each adc channel may be connected to a dual-band, digital down-converter (ddc) with up to three independent, 16-bit numerically-controlled oscillators (ncos) per ddc for phase-coherent frequency hopping. additionally, the adc is equipped with front-end peak and rms power detectors and alarm functions to support external automatic gain control (agc) algorithms.
the adc32rf45 device supports the jesd204b serial interface with subclass 1-based deterministic latency using data rates up to 12.3 gbps with up to four lanes per adc. the device is offered in a 72-pin vqfn package (10 mm × 10 mm) and supports the industrial temperature range (–40°c to +85°c).
