The ADC31RF80 device is a 14-bit, 3-GSPS, single-channel telecom receiver and feedback device that supports RF sampling with input frequencies up to 4 GHz and beyond. Designed for high signal-to-noise ratio (SNR), the ADC31RF80 delivers a noise spectral density of –155 dBFS/Hz as well as dynamic range 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.
The ADC31RF80 comes with 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 ADC31RF80 supports the JESD204B serial interface with subclass 1-based deterministic latency using data rates up to 12.5 Gbps with up to four lanes. 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).

The ADC32RF80 evaluation module (EVM) demonstrates the performance of a dual 3-GSPS 14-bit analog-to-digital converter (ADC) with the JESD204B interface. The EVM includes the ADC32RF80 device, and JESD204B clocking is provided by the LMK04828 and TI voltage regulators to provide the necessary (...)
The JESD204 rapid design IP has been designed to enable FPGA engineers to achieve an accelerated path to a working JESD204 system. The IP has been architected in a way that downstream digital processing and other application logic are isolated from most of the performance- and timing-critical (...)
This Excel calculator provides system designers a way to simplify the design and debugging of direct RF-sampling receivers. It offers three functions: frequency planning, analog filtering, and decimation filter spur location.
In the concept phase, a frequency-planning tool enables fine tuning of (...)
