Isolation Barrier Pulse Transformer
The isolation element used by the 73M1x22 is a standard digital pulse transformer. Several vendors supply
compatible transformers with up to 6000 V ratings. Since the transformer is the only component crossing
the isolation barrier other than EMI capacitors that may be required, it solely determines the isolation
between the PSTN and the 73M1922 digital interface. This method of isolation is significantly superior to
other isolation techniques with major advantages in high common mode voltage operation, lower radiated
noise (EMI) and improved operation in noisy environments. Table 28 lists some pulse transformers
compatible with the 73M1x22. The table also includes lower-voltage transformers that offer low-cost
alternatives if such voltages are sufficient.
