Note 1: Limits are 100% production tested at T
A
= +25°C. Limits over the entire operating temperature range are guaranteed by
design and characterization but are not production tested.
Note 2: This is the recommended operating frequency range. The parts have been characterized over the specified frequency
range and production tested at 900MHz. Operation outside of this range is possible but not guaranteed.
Note 3: Guaranteed by design and characterization.
