Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.

4. Measured using Test Circuit in Figure 2.

5. Dependent on crystal

6. RBW = 100kHz, OBW measured at −20dBc.
