AFE5801EVM: How to sync the AFE5801EVM with the chirps generated by the LMX2492EVM

Hi,

For your question 1,

You can see there are memory chips on TSW1400EVM board,

the AFE5801EVM with the TSW1400EVM record all the real time samples to TSW1400EVM memory.

After you capture all the real time data you needed, the through by using High Speed Data Converter Pro (HSDC Pro) GUI

which will load all the real time data to your PC.

for your question 2,

You can use you own trigger source (such as, generated by the LMX2492EVM)

please using hardware sync (i.e., Trigger Signal) input pin and refer to AFE5809 User's Guide page 12 Figure 10

for reference. That means using your own trigger source to trig AFE5801 Sync pin and TSW1400EVM's Trig input pin.

Thank you!

Hi,

for your question 1,

the real-time captured to TSW1400EVM's memory (for all 8 channel data)

but not real-time directly saved into your PC's memory.

for question 2,

you can refer more details on the AFE5809 User's Guide (please copy from the TI website) Page 12 Figure 10.

after that so you can use your LMX2491 (which is similar function as Function Generator did)

to provide SYNC (trigger) signal to AFE5801's SYNC pin and TSW1400's Trigger Input as well.

for question 3,

please refer more detail related to LMX2491EVM to TI website as below:

(since we are using TSW1400 fpga only in our EVM.)

Thank you!

Hi,

you will get more correct answers from LMX group.

Thank you!

Hi Ehud,

I think I have answered the trigger question in the following post. The output flag is CMOS level.
