NOTES
1. The RSSI output is 100% dynamically tested at 5V and +20 C over a 70dB range. First the input to pin 14 is set to
2.5mV and the RSSI current recorded Then for each step of 10dB from -40 to +30dB the current is measured again. The
current change in each step must meet the specified figure for current change. The RSSI output is guaranteed monotonic
and free from discontinuities over this range.
2. Co-channel rejection is measured by applying a 3kHz deviation, 1 kHz modulated signal at an input level to give a 20dB
SINAD ratio. Then a 3kHz deviation, 400Hz modulated signal on the same frequency is also applied and its level increased
to degrade the SINAD to 14dB.
