  • Page 2: Overview

    Overview The TSW6011EVM board provides options to send an input RF signal directly to the TR371125 or through one or two low-noise amplifiers (LNAs) by moving two resistors. Additionally, there is an option to drive two of the ADCs with an external source. This source can be single-ended (board default through a transformer) or a differential signal (from a TRF3711xxEVM, for example).

    TPS70445 I_EXT Q_EXT Figure 1. TSW6011EVM System Block Diagram Digital Processing Block Diagram The FPGA receives the digital data from the ADCs and converts it from serial to parallel format. The data are then split into two paths. One path converts the data back to unsigned serial data and determines which ADC output to route to the LVDS connector.
