Isolation Barrier Pulse Transformer
The isolation element used by the 73M1x66B 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 FXO’s 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 29 lists some pulse
transformers compatible with the 73M1x66B. The table also includes low-voltage transformers that offer
low-cost alternatives if such voltages are sufficient.
