Changes
#1
...
PL_VCCINT power supply
...
U4 replaced by TPS548A28RWWR
...
Type: PCB Schematic change
Reason: In Minimize solution footprint and cost optimization.
Impact: revised routing and components placement;Up to 15A VCCINT possible. Height profile of the module is changed.
#2 Added support of wide DDR4 SDRAM
...
packages
...
Type: PCB change
Reason: In Support of new packages of DDP DDR4 ICs.
Impact: revised routing and components placement
...
DDP DDR4 now supported.
#3 Add resistors R12 and R93
...
Type: PCB Schematic change
Reason: InAdd option to select POR_OVERRIDE level.
Impact: UsFor all standard variants R93 is fitted and R12 is not fitted. With this setting the behavior is the same as in previous revision. Custom variants 4BI21-X and 4BI41-X have R12 fitted and R93 not fitted.
#4 Unused VCCO pins
...
connected together
...
within Bank 24 and Bank44
Type: PCB Schematic change
Reason: Xilinx recomendation UG583.
Impact: UsNone.
#5
...
Signal trace lengths
...
changed
Type: PCB change
Reason: In Result of changes above.
Impact: UsChanged tracelength have to be taken into account in existing designs. The tracelength for new revision are added to the TE080X series pinout generator.
#6 Added company address, CE and WEEE symbols
...
Type: PCB Silkscreen change
Reason: In Mandantory.
Impact: UsNone.
#7 Added module orientation pointer
Type: PCB change
Reason: Correct orientation of SoM on baseboard not obvious.
Impact: Implementing a similar pointer on a carrier PCB will hopefully lower the number risk of attempts to mount mounting the module missorientedwrongly oriented.
#8 Changed resistors value of R29, R31, R35, R39, R44-R47
...
Type: BOM change
Reason: Part is end of life.
Impact: Track it pad no more available.
Note: Due to the changes above the height profile of the module is changed. Using TE0803-04 board as a replacement or in system designed for TE0803-03, review and adaption of mechanics e.g. cooling solutions have to be done. KK0803-03 is not compatible with TE083-04. A new revision of the heat spreader for revision 04 of TE0803 will be released.
