4.6.1. Internal Sinusoidal Ringing
A sinusoidal ringing waveform is generated by using an
on-chip digital tone generator. The tone generator used
to generate ringing tones is a two-pole resonator with a
programmable frequency and amplitude. Since ringing
frequencies are low compared to the audio band
signaling frequencies, the sinusoid is generated at a
1 kHz rate. The ringing generator is programmed via the
RINGFREQ,
RINGAMP,
and
RINGPHAS
RAM
locations. The equations are as follows:
For example, to generate a 60 Vrms (87 VPK), 20 Hz
ringing signal, the equations are as follows:
