Notes*:
1. dBm = Decibels above or below a reference power of 1mW into 600Ω. 0dBm=0.7746Vrms.
2. dBV = Decibels above or below a reference voltage of 1Vrms. 0dBV=1Vrms.
3. Input op-amp configured to 0dB gain at Vdd=5V+/-10%, -3dB at Vdd=3V+/-10%.
4. Mark and Space frequencies have the same amplitude.
5. Band limited random noise (200-3400Hz). Present when FSK signal present.
6. OSC1 at 3.579545 MHz ±0.2%.
