WitrynaThe matching pad models listed below match a 50 Ohm impedance system to a 75 Ohm impedance system. Resistive matching pads are wide-band devices that operate down to DC. For 50 Ohm to 75 Ohm impedance matching, the internal resistors do create 5.7dB of attenuation loss. If your impedance matching application must have … WitrynaThus the SRAM -> FPGA direction is ok - the termination impedance on the FPGA side is set to 50 ohms using DCI, to match the output impedance from the SRAM. The issue is with the FPGA -> SRAM direction. The SRAM input impedance is set to 75 ohms, but I need to be able to set the output impedance from the FPGA to be 75 ohms. So my …
