AFE7222评估模块是一个电路板，允许设计者评估德州仪器（TI）双通道AFE7222 ，低功耗模拟前端混合信号收发器的性能。该EVM提供了一个灵活的环境下的各种时钟，数据输入和IF或RF输出条件下测试的AFE7222 。DescriptionThe AFE7222EVM is a circuit board that allows designers to evaluate the performance of Texas Instruments' two-channel AFE7222, a low power analog front end mixed-signal transceiver. The AFE7222 contains dual 12-bit 65MSPS ADCs and dual 12-bit 130MSPS DACs, along with 2x/4x interpolation, /2 decimation, independent 32-bit TX/RX complex mixers, quadrature modulation correction and auxiliary monitoring/control ADC/DACs.The EVM provides a flexible environment to test the AFE7222 under a variety of clock, data input and IF or RF output conditions. For ease of use as a complete RF transmit solution the AFE7222EVM includes the CDCE72010 clock generator/jitter cleaner for clocking the AFE7222 as well as a TRF370333, a 350 MHz to 4 GHz quadrature modulator, for up converting I/Q outputs from the DAC to real signals at RF. The dual ADC in the AFE7222 is driven from transformer-coupled IF inputs for flexible receiver evaluation and measurements. The ADC input path can be configured for DC-coupled complex baseband inputs as well.The EVM can be used along with the TSW3100 to perform transmit system prototyping along with the AFE7222 integrated dual DACs. The TSW3100 generates the test patterns which are fed to the AFE7222 through a serial LVDS port. The CDCE72010 clock chip can be used to synchronize the TSW3100 board to AFE7222EVM. The TSW1200 can be used to capture data from the AFE7222 integrated dual ADCs for FFT analysis.The AFE7222EVM is also compatible with Xilinx and Altera FPGAs EVMs and design kits for rapid evaluation and prototyping. The AFE7222EVM includes an HSMC input for direct connection to HSMC compatible Altera FPGA EVMs for DAC input patterns, and the HSMC-ADC-BRIDGE can be ordered for ADC data capture using Altera FPGA EVMs. The FMC-DAC-ADAPTER and FMC-ADC-ADAPTER boards available from TI enable the connection of the AFE7222EVM to the FMC headers on Xilinx EVMs.Features
