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 TSW1400 (or TSW1405, TSW1406) to perform transmit system prototyping along with the AFE7222 integrated dual DACs. The TSW1400 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 TSW1400 board to AFE7222EVM. The TSW1400 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.
