JESD204 interface

I want to make JESD204 interface for using LTC2274 AD converter. 

But I don't know which mega function to be use. 

Teach me how and which megafunction to be use or IP for JESD204. 

 

Thank you.

You can use the JESD204 megafunction, available in Quartus 14.0 and on. Mind you, you will have to pay for it (about $10K I think), and you will need to understand the appallingly written User Guide. There is an example, but it is in Verilog or VHDL only, and understanding the linkage is difficult. A proper block diagram (not the generalised one in the UG) or capture of a Qsys block diagram would have been much better.  

 

All the same, it is now available.

Refer to JESD204b User Guide for the design steps at http://www.altera.com/literature/ug/ug_jesd204b.pdf 

Some JESD204B example designs are available at http://www.altera.com/technology/high_speed/protocols/jesd204b/je-ref-designs.html

I think probably double that based on this http://www.mouser.com/productdetail/altera/ip-jesd204b/

Hmm, it is strange. 

Xilinx has ip license which cost 1400$

It seems, that better is use the A/D converter with serial LVDS. But on datasheet 

https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/ug_altlvds.pdf 

 

i read on page 3, that i need some license too. Is it true ?  

In datasheet  

https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/ug_altera_lvds.pdf 

 

is nothing about license.... 

 

How is it ?:)

Page 3 is just a generic section they put in all of the IP cores. AFAIK the LVDS megafunction is free.
