Operating Characteristics
For the following conditions unless otherwise specified:
Xtal Frequency = 3.579545MHz, S/N = 16dB, Noise Bandwidth = 5kHz,
VDD = 3.0V to 5.0V, Tamb = -40°C to +85°C. 0dB = 775mVrms.

Notes:
1. Not including any current drawn from the detector pins by external circuitry.
2. Small signal impedance over the frequency range 100Hz to 2000Hz and at VDD = 5.0V.
3. Timing for an external input to the XTAL/CLOCK pin.
4. Input signal level at VDD = 5.0V, scale signal for different VDD.
5. ENABLE pin.
6. DETECT pin.
7. Nominal values which are subject to dynamic tolerances within the signal analysis process,
as a result of using stochastic signal processing techniques.
