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:
Parts are production tested at T
A
= +25°C; Min and Max values are guaranteed by design and characterization.
Note 2:
BER = 2E-3, Manchester encoded, data rate = 4kbps, IF bandwidth = 350kHz.
Note 3:
Input impedance is measured at the LNAIN pin. Note that the impedance includes the 15nH inductive degeneration
