Texas Instruments DAC39RF20 | Demoboard DAC39RF20EVM

Description

The DAC39RF20EVM is an evaluation module (EVM) for evaluating the DAC39RF20 family of digital-to-analog converters (DACs) from Texas Instruments. The EVM can be used to evaluate the performance of the DAC up to 22GSPS sampling rate. The EVM is designed to work with the field-programmable gate array (FPGA)-based pattern generator card TSW14J59EVM. The available FPGA Mezzanine Card (FMC) connector on the EVM also makes interfacing the DAC to FPGA development boards from third-party vendors possible. An easy-to-use software interface GUI to control the DAC and an onboard LMK04828 clock chip through serial peripheral interface (SPI) are also available.

Features

• Two balun-coupled output networks per DAC output allowing singled ended signal evaluation
• A 5MHz to 10GHz low band balun for first Nyquist evaluation
• A 2GHz to 18GHz high band balun for second and third Nyquist evaluation
• A LMK04828 clock distribution chip for distributing FPGA reference clocks and SYSREF for subclass 1 operation
• A balun-coupled clock input network to test the DAC performance with an external low-noise clock source
• An FMC+ with high-speed serial data connections for full JESD204C testing of all 16 lanes
• A USB to serial chip to allow programming of the DAC or LMK with a simple USB connection
• The ability to program the DAC or LMK from an FPGA using the FMC+ connector
• Device register programming through USB connector and FTDI USB-to-SPI bus translator with option to program from FGPA using SPI through FMC+ connector

Typical applications

• Wireless Communications Testers
• Satellite Communications (SATCOM), Phased Array Antenna Systems, Synthetic Aperture Radar (SAR) Exciter
