Notes:
1. Measured into 50Ω resistive load
2. For 1kbps Manchester encoded; the data bit rate is limited to 3kbps NRZ max. to meet adjacent channel
power specification.
3. Total over full supply and temperature range
4. With 0V – 5.0V modulation input
5. Other VHF 120-180MHz by special order
6. 5V CMOS compatible
7. To achieve specified FM deviation
