Forum Post: RE: Help needed in interfacing and testing ADS54RF63EVM

Hi,

you will need to have a high quality signal source for generating a sample clock to supply to the ADS54RF63 EVM and a high quality signal source to generate an input signal to the analog input of the EVM.   I stress the need for a high quality signal source because phase noise (or jitter) on the signal sources will limit the signal to noise ratio that you can observe from your ADS54RF63 EVM.

You will need to have a way of capturing the sample data from the EVM so that you can evaluate the data or do some kind of processing of the data to fit your needs.  The easiest way to capture the digital sample data is with one of our FPGA-based capture cards such as the low cost TSW1405 or the more fully featured TSW1400.  Take a look at the web pages for these two capture cards and take a look at the User's Guide for the High Speed Data Converter Pro software that is used with these two capture cards to see what they can do.

Since you have a Xilinx development platform you could also use the FMC-ADC-ADAPTER http://www.ti.com/tool/fmc-adc-adapter to connect the EVM straight to your development platform, but then you would have to create your own Xilinx firmware to capture the data from the ADC and so something with it.  We don't provide firmware for your development platform.

The breakout board that you mentioned is for connecting the sample outputs of the EVM up to a logic analyzer to capture the sample data.  The breakout board has landings for a Tektronix or an Agilent logic analyzer pod to connect to the signals, but you would have to have the logic analyzer, the logic analyzer pod, and the logic pod mounting shell that solders to the breakout board for your particular pod.  We don't pre-install the logic pod shell on the breakout board because we don't know what logic analyzer you might be using. 

For signal sources there is also one more option:  TI has a low-cost system evaluation kit (HSDC SEK-10) that can provide a clean (filtered) 10MHz signal for the analog input http://www.ti.com/tool/tsw2110evm and a clean sample clock for the clock input http://www.ti.com/tool/tsw4806evm.  The low cost tools may be purchased as a kit or as indivudual pieces.  The User Guide and video at the links above give more information about these low cost tools.

Regards,

Richard P.
