(1) All differential clock inputs comply with the LVDS Electrical Specification, IEEE 1596.3-1996 and all SerDes I/Os comply with the XAUI Electrical Specification, IEEE 802.3ae-2002.
(2) All SerDes I/Os comply with the XAUI Electrical Specification, IEEE 802.3ae-2002.
(3) Users are required to program their board CVDD supply initial value to 1.0 V on the device. The initial CVDD voltage at power-on will be 1.0 V nominal and it must transition to VID set value, immediately after being presented on the VCNTL pins. This is required to maintain full power functionality and reliability targets ensured by TI.
(4) SRVnom refers to the unique SmartReflex core supply voltage that has a potential range of 0.8 V and 1.1 V which preset from the factory for each individual device. Your device may never be programmed to operate at the upper range but has been designed accordingly should it be determined to be acceptable or necessary. Power supplies intended to support the variable SRV function shall be capable of providing a 0.8 V-1.1 V dynamic range using a 4- or 6-bit binary input value which as provided by the DSP SmartReflex output.
(5) Where x = 1,2,3,4... to indicate all supplies of the same kind.
(6) For USB High-Speed, Full-Speed, and Low -Speed modes, USB I/Os adhere to Universal Serial Bus, revision 2.0 standard. For USB Super-Speed mode, USB I/Os adhere to Universal Serial Bus, revision 3.1 specification, revision 1.0 standard.
