I have a design that includes a TS201 DSP, SDRAM, embedded FLASH memory and FPGA(virtex4). I want to connect the data wires to each of them with a star topology. Each of the ICs has the capability of transmitting and receiving signals so all the pins are transceivers. I have applied a series termination to all pins. For example for dsp a series resistor of 18ohms, for SDRAM a series resistor of 22 ohms, for FPGA and FLASH memory again 22 ohms. The results are pretty good with sigxplorer but I want to ask if this kind of termination is used practically in the designs.Else what kind of terminations can be used.
I want your advices. Thank you very much
