Ti135 Programmable Duty Cycle

Ti135 FPGAs support a programmable duty cycle on the CLKOUT1 signal. A programmable duty cycle means that the clock's highs and lows can be different lengths (see Figure 1).

If you turn on output clock inversion, the duty cycle setting is applied before the clock is inverted.

Important: You cannot use the programmable duty cycle at the same time as the fractional output divider.
