双通道、14 位、3GSPS 射频采样模数转换器 ADC 72-VQFN -40 to 85
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 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 can 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 supports the JESD204B serial interface with subclass 1-based deterministic latency using data rates up to 12.5 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.
