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,

If I understand you correctly, you are referring to the frequency and IO standard of the crystal for the GXB refclk. For your information, the CV GXB refclk support frequency from 27MHz - 550MHz and the IO standard supported are 1.2 V PCML, 1.5 V PCML, 2.5 V PCML, Differential LVPECL, HCSL, and LVDS. You may refer to the device datasheet for further details. Thank you.
