Operating Limits
All device characteristics are measured under the following conditions unless otherwise specified:
VDD = 3.3V. TAMB = 25°C. Xtal/Clock f0 = 1.0MHz. Signal 0dB ref: = 180mVrms.
Composite Signal = 1.0kHz Audio Tone at 0dB, Noise at –12.0dB (gaussian white noise, band-limited to
6.0kHz), Programmed CTCSS Tone at -20dB.
