APPLICATION INFORMATION
Application Circuit
Analog Interface
The application circuit of the W91030B in Figure 9-1 shows the device being used within a typical
CPE system. Note that only the circuit between the W91030B and the line interface is shown. The
gain control op-amp is set to unity gain to allow the electrical characteristics to be met in this
application circuit. It should also be noted that if a glitch with sufficient amplitude appears on the tip
and ring interface, this will be detected as a ringing input by this circuit.

Figure 9-1 Application Circuit
Another application circuit for the W91030B, which provides common mode rejection of ringing circuit
signals, is shown in Figure 9-2. When the AC voltage between the tip and ring is greater than the
zener diode breakdown voltage, the photo-coupler LED will turn on, driving RNGDI high and thus
detecting a ringing signal. Note however in this case, a glitch on the tip and ring interface is not able
to turn on the photo-coupler and therefore will not be detected as a ringing signal.
