4-transmit, 4-receive RF-sampling transceiver, 5-MHz to 7.4-GHz, max 400-MHz IBW

Overview

TopologyDAC
IC revisionA

Description

The AFE7900 family evaluation module (EVM) is a flexible RF-sampling transceiver platform that can be configured to support up to four-transmit, four-receive, and two-feedback (4T4R+2FB) channels simultaneously. The EVM interfaces with the TI pattern/capture card solution shown below (sold separately), as well as many FPGA FMC-compliant development kits.

Features

Evaluate 1T1R to 4T6R RF-sampling AFE79xx configurationsJESD204B/C data interface to simplify digital interface; compliant up to 29.5-Gbps lane ratesSupports JESD204B/C for synchronization and compatibilityOption for DC-DC-based LDO-less power-management solutionOnboard clocking solution supported with LMK04828 and for generating SYSREFOn-chip interpolation/decimation filter inputs/outputs sample data at reduced sample rates and improved signal-to-noise ratio (SNR)
