    Hello Hsiao,

    Yes, every channel is able to operate at different data rate. Channel A and B are fully independent and their application rates and references clocks are separate.

    Hi Hsiao,

    Channel A
    Data Rate = 9.8304Gbps / REFCLK = 122.8 - 125Mhz /Full Rate
    HS_PLL_MULT[3:0] ==> 1101 (x20)
    HS_RATE_TX[1:0] ==> 00
    HS_RATE_RX[2:0] ==> 000

    Channel B
    Data Rate = 2.4576Gbps / REFCLK = 122.8 - 125Mhz /Quarter Rate
    HS_PLL_MULT[3:0] ==> 1101 (x20)
    HS_RATE_RX[2:0] ==> 110
