(1) Developed for Functional Safety applications, the device supports hardware integrity up to SIL-2. Refer to the related documentation for more details. Non-Functional Safety Variants are also available for these devices.
(2) 3 Tx Simultaneous operation on the applicable devices is supported only with 1V LDO bypass and PA LDO disable mode. In this mode, the 1V supply needs to be fed on the VOUT PA pin.
(3) As the certification may get secured at different times and post certificate the target would be updated to “compliant” from “compliance targeted” only in related datasheets, please refer to the respective datasheets for most recent compliance status.
(4) Device security features including Secure Boot and Customer Programmable Keys are available in select devices for only select part variants as indicated by the Device Type identifier in Section 3, Device Information table.
(5) 6 bits linear Phase Shifter.
(6) PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty.
