Low Voltage CTCSS Encoder/Decoder
14
MX465
16. Max composite signal is 3.5dB with:
Noise (band limited 6kHz Gaussian) = -12dB ref to 1kHz test tone
f0 CTCSS tone = -20dB ref to 1kHz test tone
17. For maximum dynamic range, set audio level to 0dB, VDD x150mVRMS, using minimum VDD under
which system is intended to work. (e.g. for a 2.7V system, use 0dB equal to 405mVRMS).
18. By characterization only.
19. Batch sampled only
20. For example, if: f0 = 100.0Hz (f0-1 = 97.4Hz f0+1 = 103.5Hz)
