automatically assigns a seventeenth channel as the transmitter clock
output. You can edge- or center-align the transmitter clock output by
selecting the default PLL phase or selecting the 90° phase of the PLL
output. On the receiver side, the clock signal is connected to the receiver
PLL's clock input, and you can assign identical clock-to-data alignment.
The multiplication factor W is calculated automatically. The data rate is
dividing by the input clock frequency to calculate the W factor. The
deserialization factor J may be 4, 7, 8, or 10.
