2.8.3. Reference Clock Frequency
Valid values for reference clock frequency change with the data rate but the reference input clock frequency must be within 50 MHz and 622 MHz. Range of supported reference clock frequency is dependent on device. Please refer to the device datasheet for range of supported frequency for every device.
The general formula to determine frequency:
Frequency = p×Data Rate/(2×m)
where p = 1 or 2, and m = 4, 5, 8, 10, 16, 20, or 25
Condition for frequency to be valid:
(50×p) < Frequency < 622
