Output Data Formatting

Each output channel’s data can be formatted in five different ways:

●     No Return: The output logic level stays either high or low for the duration of the clock period (default).

●     Return to Zero: The signal returns to zero between consecutive data clocks at 50% of the specified output frequency clock duty cycle. This takes place even if a number of consecutive 0's or 1's occur in the signal. The signal is self-clocking and does not require any additional settings.

●     Return to One: The signal returns to one between consecutive data clocks at 50% of the specified output frequency clock duty cycle. This takes place even if a number of consecutive 0's or 1's occur in the signal. The signal is self-clocking and does not require any additional settings.

●     Return to Hi-Z: The signal returns to Hi-Z between consecutive data clocks at 50% of the specified output frequency clock duty cycle. This takes place even if a number of consecutive 0's or 1's occur in the signal. The signal is self-clocking and does not require any additional settings.

●     Return to Complement: The Return to Complement (also called Manchester code) format ensures that each transmitted data bit has at least one transition at 50% of the specified output frequency clock duty cycle. It is, therefore, self-clocking, which means that a clock signal can be recovered from the encoded data. Return to Complement ensures frequent data transitions which are directly proportional to the clock rate which helps clock recovery. A logic low is expressed by a low-to-high transition. A logic high is expressed by high-to-low transition. The transitions which signify logic high or low occur at the midpoint of a period, the direction of the mid-bit transition indicates the data.
