Using the RSSI Pin

The receiver’s Received Signal Strength Indicator (RSSI) line serves a

variety of functions. This line has a dynamic range of 80dB (typical) and

outputs a voltage proportional to the incoming signal strength. It should be

noted that the RSSI levels and dynamic range will vary slightly from part

to part. It is also important to remember that RSSI output indicates the

strength of any in-band RF energy and not necessarily just that from the

intended transmitter; therefore, it should be used only to qualify the level

and presence of a signal.

The RSSI output can be utilized during testing or even as a product feature

to assess interference and channel quality by looking at the RSSI level

with all intended transmitters shut off. The RSSI output can also be used

in direction-finding applications, although there are many potential perils to

consider in such systems. Finally, it can be used to save system power by

“waking up” external circuitry when a transmission is received or crosses a

certain threshold. The RSSI output feature adds tremendous versatility for

the creative designer.
