Texas Instruments TSW1265 Dual Receiver Reference Design

Texas Instruments TSW1265 Wideband Dual Receiver Reference Design is an evaluation platform that is ideally suited for use as a feedback receiver for transmitter digital predistortion. Each evaluation module signal chain contains a complex demodulator (LMH6521) and ADS5402 12-bit ADC. The signal chain can be configured for a variety of frequency plans by modifying the on-board filter components. Both evaluation boards also include the LMK04800 dual-PLL clock jitter cleaner and generator to provide an on-board low-noise clocking solution. A software GUI is provided to allow for configuration of the ADS4249 and LMK04800. The gain of the LMH6521 DVGA can be controlled through the GUI or alternatively through the high speed connector with an FPGA. The evaluation module is designed to mate with the TSW1400EVM pattern capture and generation board to capture data from the ADS4249. Signal analysis can then be performed with the High Speed Data Converter Pro software tool.
