ARRIER DETECTOR THRESHOLD PROGRAMMING
When the LBD active register = 0, the carrier detector is enabled and the signal CDout is sent to the output pin CDLBD.
If RSSI is above the programmed RSSI level, CDLBD = 0; if RSSI is below the programmed level then CDLBD = 1. The
carrier detector gives an indication if a carrier signal is present on the selected channel. The carrier detector has a
nominal value and tolerance, if a different carrier detect threshold value is desired, this can be programmed through the
microcontroller interface. If the carrier detect range is to be scaled, an external resistor should be connected between
pin RSSI and ground. CD control = 10011 which corresponds to RSSI = 0.86 V (typical DC value).
