Termination resistors | Cypress Semiconductor
I am designing a FX3 board with Spartan 6 FPGA.
My question is: "Do I need 22 Ohm termination resistors on GPIF 2 interface".
I couldn't make a signal integrity simulation since there is no ibis model of the FX3 chip.
The PCB will be very small. FX3 and Spartan 6 will be very close to each other.
Nearly all GPIF pins will be connected to the FPGA.
