Notes:
1. Measured into 50Ω resistive load.
2. Exceeds EN/EMC requirements at all frequencies.
3. Total over full supply and temperature range.
4. With 0V – 3.0V modulation input.
5. To achieve specified FM deviation.
6. Dependent upon TXD conditions during power-up.
7. See applications information for further details.
