(1) Developed for Functional Safety applications, the device supports hardware integrity up to ASIL-B. Refer to the related documentation for more details.
(2) 3 Tx Simultaneous operation is supported only in AWR1843 and AWR2243 with 1V LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin.
(3) The LVDS interface is not a production interface and is only used for debug
(4) PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of the Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
