High speed serial interface

Hello

I am trying to communicate between two FPGAs. What are the possible high speed serial or parallel interfaces that can be use to realize the same.

Re: High speed serial interface

hi mummy@papa3 ,

 

I believe and assume your using the Spartan 6 FPGA , which consists of GTP transceivers. which  are used in Ultra-fast data transmission between ICs, over the backplane, or over longer distances is becoming increasingly popular and important. It requires specialized dedicated on-chip circuitry and differential I/O capable of coping with the signal integrity issues at these high data rates.

All Spartan-6 LXT devices have 2–8 gigabit transceiver circuits. Each GTP transceiver is a combined transmitter and receiver capable of operating at data rates up to 3.2 Gb/s. The transmitter and receiver are independent circuits that use separate PLLs to multiply the reference frequency input by certain programmable numbers between 2 and 25, to become
the bit-serial data clock. Each GTP transceiver has a large number of user-definable features and parameters. All of these
can be defined during device configuration, and many can also be modified during operation.

Re: High speed serial interface

Thanks Sir

I am planning to use 2 SoCs having Ultrascale fabric. What is the circuitry and the high speed interface required to achieve in communication between these devices.

hello mummy@papa3 ,

 

what is the protocol you planned to use in-between 2soc for the interface

mummy@papa3 

I would recommend looking at using the Aurora IP to handle the transfer of data from one FPGA to another.  Here is a link to the user guide:
