Description
An auxiliary, selectable tone frequency output, providing a square wave
CALibration signal from the Tone 2 Generator or a sine wave CUES (beep)
signal from the Summing Amplifier. The output mode (CAL or CUES) is
selected by Bit 14 in the TX Tone Generator 2 Register (Table 5). When Tone
Generator 2 is set to Notone, the CAL input is pulled to V
BIAS
; during a
powersave of Tone Generator 2 it is held at V
SS
.
Input to the on-chip Summing Amplifier. This amplifier is available for
combining Tone 1 and Tone 2 outputs (DTMF). Gain and coupling components
should be used at this input to provide the required system gains. See Figure 2
and Figure 3
Output of the on-chip summing amplifier. Combined tones (1 and 2) are
available at this output. See Figure 2 and Figure 3.
This is the combined tone output available for transmitter modulation. The
switch allows control of the MX803A output. Control of this switch is by Bit 4 of
the Control Register. See Figure 2 and Figure 3.
C-BUS serial clock input. This clock, produced by the
μ
C, is used for transfer
timing of commands and data to and from the MX803A. See Figure 8 and
Figure 9.
Positive supply. A single +5 volt power supply is required. Levels and voltages
within this Audio Signaling Processor are dependent upon this supply..
No Internal Connection. These pins may be connected to V
SS
to improve
screening and reduce noise levels around the MX803A.
