JESD204B Lanes

Dear Support and Expert, 

 

While I am reading the "JESD204B Intel® FPGA IP User Guide" 21.3. 

 

it claims in the core features "• Single or multiple lanes (up to 8 lanes per link)" 

I don't quite understand this 8 lanes per link limit. 

I have a design from Texas Instrument,  the parameters of the IP core use 16 lanes in 1 link(I guess). 

 

can anyone familiar with JESD204B core, give me some suggestion. how to understand the 8 lane per link limit.

 

thank you,

David

Hi David,


Good Day.

Thank you for your patience.

You may refer to chapter 2.3, and 2.5 of the JESD204B Intel FPGA IP User Guide for more details.

I believe you are talking is the Lanes per converter device.

In your case, your project require 16 lanes, hence, you will need 2 converters.


Thank you.


Best Regards,

Hi David,

 

Below is the link to JESD204B Intel FPGA IP User Guide:

JESD204B Intel® FPGA IP User Guide 

 

Below here is the link to AN803 documentation. Under documentation, you may refer to figure 3 & 4 for examples of converters:

AN803: Implementing Unsynchronized ADC Multi-Link Design with JESD204B RX IP Core 

 

Thank you.
