I need to drive one of the Si53305 inputs from the external PCIe cable (CREFCLK). CREFCLK is AC-coupled at the source (PC motherboard), then it goes through 2 meter PCIe external cable and comes to Si53305 input. I assume I only need the 100 Ohm resistor between CLK+/CLK- but no additional AC-coupling on Si53305 input. Is my assumption correct?
The 2nd or additional AC coupling is not required, correct
