Notes
The AMI inputs <I_1> and <I_2> should be connected to the external AMI clock source by 470 nF coupling capacitor
C1.
The AMI differential output TO8POS/TO8NEG should be coupled to a line transformer with a turns ration of 3:1.
Components C2 = 470 pF and C3 = 2 nF. If a transformer with a turns ratio of 1:1 is used, a 3:1 ratio potential
