TEXAS INSTRUMENTS AFE7222EVM 评估模块, 数据转换器, AFE7222
The is a circuit board that allows designers to evaluate the performance of two channel AFE7222, a low power analog front end mixed signal transceiver. The AFE7222 contains dual 12bit 65MSPS ADCs and dual 12bit 130MSPS DACs, along with 2x/4x interpolation, /2 decimation, independent 32bit TX/RX complex mixers, quadrature modulation correction and auxiliary monitoring/control ADC/DACs. The evaluation module 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 evaluation module includes the CDCE72010 clock generator/jitter cleaner for clocking the AFE7222 as well as a TRF370333, a 350MHz to 4GHz 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.
