† AC Electrical Characteristics are over recommended operating conditions, unless otherwise stated.

‡ Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.

Notes*:

1. dBm = Decibels above or below a reference power of 1 mW into 600 Ω. 0 dBm = 0.7746 Vrms.

2. dBV = Decibels above or below a reference voltage of 1 Vrms. 0 dBV = 1 Vrms.

3. Input op-amp configured to 0 dB gain at Vdd = 5 V+/-10%, -3 dB at Vdd = 3 V+/-10%.

4. Mark and Space frequencies have the same amplitude.

5. Band limited random noise (200-3400 Hz). Present when FSK signal present.

6. OSC1 at 3.579545 MHz ±0.2%.
