ADC32RF8x Wideband Receiver & Feedback IC

Texas Instruments ADC32RF8x Wideband Receiver & Feedback IC is a 14-bit, 3GSPS, dual-channel telecom receiver and feedback device family that supports RF sampling with input frequencies up to 4GHz and beyond. The ADC32RF8x is designed for high signal-to-noise ratio (SNR) and delivers a noise spectral density of –155dBFS/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 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.
