4. AOUT PWM Output
Figure 19 illustrates an optional circuit to support the
pulse width modulation (PWM) output capability of the
Si3050 for call progress monitoring purposes. To enable
this mode, the INTE bit (Register 2) should be set to 0,
the PWME bit (Register 1) set to 1, and the PWMM bits
(Register 2) set to 00.
Figure 19. AOUT PWM Circuit for Call Progress
Registers 20 and 21 allow the receive and transmit
paths to be attenuated linearly. When these registers
are set to all 0s, the transmit and receive paths are
muted. These registers affect the call progress output
only and do not affect transmit and receive operations
on the telephone line.
The PWMM[1:0] bits (Register 1, bits 5:4) select one of
three different PWM output modes for the AOUT signal,
including a delta-sigma data stream, a 32 kHz return to
0 PWM output, and a balanced 32 kHz PWM output.
