notes:
1. For 6dB (S+N)/N degradation on wanted -100dBm signal
2. Receiver spurious responses are at FRF ± (n×15.92MHz), n=1,2,3 etc.
3. Average over 30ms (14kbps), 3ms (40kbps), 1ms (160kbs) at maximum bit rate.
4. Values for 50:50 mark to space (i.e. square wave)
Module test circuits
Fig.5: TX2 test circuit
Fig.6: RX2 test circuit
The PNP transistor (e.g. BC558B) enables a CMOS compatible Carrier Detect signal to be derived from pin 3. If no
CD signal required pin 3 should be connected directly to pin 5 (Vcc).
