Part Number: ADC12DJ5200RF Is the device clock A)4GHz under the following conditions? Or is it B)2GHz? For example, I want to transmit 12 bits of data per symbol at 4GSps. The sampling frequency is 4GHz. A) At this time, 4 tail bits are added to 5 symbols (60 bits) in the transport layer, Considering 8b/10b conversion, 48Gbps * 64/60 * 1.25 = 64Gbps When transmitting with 8 lanes, the data rate is 8 Gbps per lane (lane_rate) When JMODE = 0, it operates in single channel mode and the sampling rate is twice the device clock, so I calculated that the device clock would be 4GHz. But, I can think differently. B) glbl_clk = lane_rate / 40 = 200MHz device clock = sample_rate / 2 = 2GHz
