AC ELECTRICAL CHARACTERISTICS
T
= -45dBm; FM modulation = 576kHz with 288kHz peak deviation, discriminator tank circuit Q=4. The parameters listed below are tested using
automatic test equipment to assure consistent electrical characteristics. The limits do not represent the ultimate performance limits of the
device. Use of an optimized RF layout will improve many of the listed parameters.
