(1) 3 Tx Simultaneous operation is supported only with 1-V LDO bypass and PA LDO disable mode. In this mode, the 1-V supply needs to be fed on the VOUT PA pin.

(2) LVDS Interface is not a production Interface and is only used for debug.

(3) JTAG is used for Boundary SCAN purposes.

(4) PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty.

(5) QSPI interface is only used for development and is not supported in production

(6) Developed for Functional Safety applications, the device supports hardware integrity upto SIL-2. Refer to the related documentation for more details.
