Figure 18 AMI Input and Output Signal Levels
Figure 19 Recommended Line Termination for AMI Output/Output Ports
The AMI inputs I1 and I2 should be connected to the external AMI clock source by 470 nF coupling capacitor C1.
The AMI differential output TO2POS/TO2NEG should be coupled to a line transformer with a turns ratio 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
divider R
must be used to achieve the required 1 V pk-pk voltage level for the positive and negative pulses.
