DAC87J82 and DAC87J84 Eye Scan

Other Parts Discussed in Thread: DAC37J82

Is there an example project or example code that shows how to perform an Eye Scan with the DAC87J82?

Eye Scans appear to use the JTAG interface; is there Windows or Linux software that you recommend for writing to the JTAG interface?

Thanks,

Hi Jim,

That document gives me a low-level description of how to access the RX ADTM. That's good.

I am also looking for software recommendations for performing the access. Is there Windows (or Linux) software that you recommend I use for sending the custom JTAG commands?

For example, does TI have a JTAG pod/software combination that allows me to talk to the IEEE 1500 bridge or RX ADTM?

Thanks,

- Ian
