Hello! the datasheet of AN70707 recommends using 22-Ω series termination resistors to avoid reflection on these lines. When FPGA is close to CYUSB3014(about 40mm), can I leave out the 22-Ω series termination resistors to make it convenient?

Hi,
It is recommended irrespective of the length of the traces.

Hi Madhu Sudhan,
I understand that it is recommended irrespective of the trace length. But is it necessary for all GPIF II lines or just the DQ and CTL lines?
Also should it be placed close to FX3 or the FPGA/ASIC?
Thanks,
Harshad.
