Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
100% tested at T
A
= +125°C. Guaranteed by design and characterization over entire temperature range.
Note 2:
IRSEL is internally set to 375MHz IR mode. It can be left open when the 375MHz image-rejection setting is desired. Bypass
to AGND with a 1nF capacitor in a noisy environment.
Note 3:
Peak power level. BER = 2 x 10-3, Manchester encoded, data rate = 4kbps, IF bandwidth = 280kHz.
Note 4:
The voltage conversion gain is measured with the LNA input matching inductor and the LNA/Mixer resonator in place, and
does not include the IF filter insertion loss.
Note 5:
Crystal oscillator frequency for other RF carrier frequency within the 300MHz to 450MHz range is (f
