Adjacent Channel Sensor
The adjacent channel sensor is active in FM mode only and measures the field strength outside
the reception band.

PIN 10 (ADJAC)
Bit 6 allows a resets of the multipath sensor and the adjacent channel sensor by connecting
pin 10 and pin 40 internally to ground and so the external capacitors can be discharged very
quickly.

Multipath Sensor
The multipath sensor is active in FM mode only and measures the disturbance due to multipath
reception. The multipath sensor detects drops in the field strength after the integrated band filter
by calculating the difference between an averaged maximum field strength and the current field
strength. The maximum depth of these drops is represented by the voltage of the peak detector
at pin 40 (MULTIP). The level of this voltage represents the degree of disturbance in the
received signal.
