I use the FPGA of cyclone V which type is 5CGXFC3B7F23C8N ,which has 1 GXB Bank （3 transceiver channel）,CH0/CH1/CH2，but CH1 has error

I download the design example “cv_GX_1ch_40b_3125mbps”，change the chip to mine（ 5CGXFC3B7F23C8N），the Channel 1 has error，how can I do？

​Hi,

The CV GXB refclk support IO standards ie 1.2 V PCML, 1.5 V PCML, 2.5 V PCML, Differential LVPECL, HCSL, and LVDS. You may select the IO standard based on your target requirement ie protocol compliant or the oscillator that you are using. You may refer to the device datasheet for further details on the CV refclk specs when cross check with the oscillators.
