DIGITAL OUTPUT

 A differential input signal of 0V will ideally produce a stream of ones and zeros that are high 50% of the time and low 50% of the time. A differential input of +2V produces a stream of ones and zeros that are high 80% of the time. A differential input of –2V produces a stream of ones and zeros that are high 20% of the time. The input voltage versus the output modulator signal is shown in Figure 6.

 

上面这段话是以2.5v作为参考电压,我可以用5v吗?如果用成5v的,那么0v时会输出50%的波吗?5v是全高吗?求解答

Van Yang:

内部参考源2.5V。请参考手册第2页,不支持5V参考源输入。
