Note:
1. Tone Follower or Packet mode enabled; see Table 3
2. Tristate selected; see Table 3.
3. With adherence to Signal-to-Voice and Signal-to Noise specifications.
4. 12kHz and/or 16kHz system.
5. With Input Amp gain setting = 0dB.
6. Time taken to change between any two of the operational modes: Tone Follower, Packet or Tristate, and with a
maximum capacitive load of 30pF on an output.
7. The time delay, after a valid serial data load (or after device powerup), before the condition of the outputs can be
guaranteed correct.
8. Immunity to false responses and/or de-responses.
9. Common Mode SPM and balanced voice input signal.
10. With SPM and voice signal amplitudes balanced; to avoid false de-responses due to saturation, the peak-to-peak
voice + noise level at the output of the Input Amp should be no greater than the dynamic range of the device. For
this reason, the signal-to-voice figure at the AMP Output will vary with the sensitivity setting. The lowest
signal-to-voice figure occurs at the highest sensitivity setting. (Table 4 27dB)
