The following picture depicts a typical example of the FPD-Link II serial stream. This
snapshot was taken with a differential probe across the 100 ohm termination resistor R1
on the DS99R106 Rx evaluation board. R1 is the termination resistor to the RxIN +/-.
Note: The scope was triggered, with a separate probe, on TCLK, the input clock into the
DS99R105 Tx. To view the serial stream correctly, do not trigger on the probe
monitoring the serial stream.
