(1) 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 under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) A_VDD is an internal 1.8-V supply derived from a regulator in the CXD9890Q chip. Pin XTALI is the only CXD9890Q input that is
referenced to this 1.8-V logic supply. The absolute maximum rating listed is for reference; only a crystal should be connected to XTALI.
(3) D_VDD is an internal 1.8-V supply derived from regulators in the CXD9890Q chip. D_VDD is routed to– DVDD_BYPASS_CAP – to provide
access to external filter capacitors, but should not be used to source power to external devices.
(4) Pin XTALO is the only CXD9890Q output that is derived from the internal 1.8-V logic supply A_VDD. The absolute maximum rating listed
is for reference; only a crystal should be connected to XTALO. A_VDD is also routed to – AVDD_BYPASS_CAP – to provide access to
external filter capacitors, but should not be used to source power to external devices.
