How to capture data from AFE's ?

Hi Derek,

We have received your post regarding the application use case of AFE5801 / LM98725 and I have assigned it to the device application expert. He will get back to you soon with any updates on this.

Hi Derek,

How are you?

If you are using AFE5801EVM, please look at the AFE5801EVM Evaluation Module

at www.ti.com/.../afe5801evm.

and then please look at the User guides at

AFE5801 8-Channel Varable Gain Ampl w/Octal High-Speed ADC (Rev. B)

You can see we connect our AFE5801EVM to TSW1400EVM (fpga inside) through a board adapter.

Thanks and best regards,

Chen

Thanks for the response,
Yes, I understand that, and in fact I am using the TSW1400EVM with the AFE5801EVM to evaluate the AFE5801 chip, however, I am asking can you use an LVDS Frame Grabber with the AFE5801 or LM98725 to capture their output if I don't want to use the TSW1400EVM

thanks

Hi Derek,

Thanks for using AFE5801EVM with TSW1400EVM.

AFE5801 device output includes Bit Clock, Frame Clock, and LVDS Output Data (Bit by Bit).

inside TSW1400 is fpga Altera Stratix which can capture the above signals and

convert the captured data and save into the memory RAM on TSW1400EVM.

Please need to make sure if your Frame Grabber can capture high speed Bit Clock sent out by AFE5801.

The Bit Clock Freq max = 6 * 65MHz speed.

Since we are only using fpga to acquire high speed data, unfortunately we don't support the PC capture card.

Thanks for using AFE5801 device!

Best regards,

Chen

Hi Derek,

We have one good document to explain how our TSW EVM works (designed for LVDS capture)
to capture AFE5801 device LVDS data.
You can find this LVDS app note (sbaa205) in the TI web site.

Thank you for using AFE5801 device.

Best regards,

 Ok, Thanks for all the help.
