Operating Limits
All device characteristics are measured under the following conditions unless otherwise specified:
VDD = 3.3V to 5.0V. VSS = 0V. TAMB = 25°C. Xtal/Clock = 4.0MHz 100ppm. 0dB ref: = 750mVrms (proportional to
VDD, see Note 16.)
Composite Signal = 1.0kHz Test Tone at 300mVrms, Noise at 75mVrms (gaussian white noise, band-limited to
6.0kHz), Programmed CTCSS Tone at 30mVrms, fo = 100Hz.
