Changes
#1 Changed DDR4 SDRAM (U2, U3) from K4A8G165WB-BIRC to K4A8G165WC-BITDTCV.
...
Impact: DDR timing needs to be considered in customer design. Trenz Reference Design reflects it without changing timing but custom firmware needs to be checked and eventually updated by customer.
#2 Changed DDR4 SDRAM (U2, U3) from K4AAG165WB-MCRC0CV to MT40A1G16TB-062E IT:F, set termination resistor (R94) from fitted to not fitted, and
...
changed resistor (R68, R69) from 240 Ohm to 0 Ohm.
Type: BOM change
Reason: BOM Optimization.
...
Reason: Improved SPI interface usage with different flashs.
Impact: None.
#17
...
Added additional decoupling capacitor (C144, C178, C186
...
... C189).
Type: Schematic Change
Reason: Improve power supply decoupling.
...
Reason: BOM Optimization.
Impact: None.
#19 Changed capacitor (C12
...
... C16, C45, C49, C52, C53, C57) from 4.7 µF, 6.3 V, to 10 µF, 10 V.
Type: Schematic Change
Reason: AMD recommendation.
Impact: None.
#20 Changed 10 µF capacitor (C2,
...
C18, C20, C22, C37, C41, C48,
...
C82, C89, C92, C94,
...
C95, C107, C130, C132, C134) from 16 V, 0603 to 10 V, 0402.
Type: Schematic Change
Reason: BOM Optimization.
...
Reason: AMD recommendation.
Impact: None.
#23 Changed 47 µF capacitor (C24, C25, C27, C33, C34, C88, C96, C110) from 0805 to 0603.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#24 Changed ferrid bead (L1
...
... L3, L5, L7, L9
...
... L12)
...
from BKP0603HS121-T to MPZ0603S121HT000.
Type: BOM Change
Reason:EOL of component.
...
Reason:BOM Optimization.
Impact: None.
...
#26 Changed net "PG_PS_LP" to "PG_PSLP_INTIO", net "PS_AVCC" to "PS_MGTRAVCC", net "PG_AVCC" to "PG_MGTRAVCC", net "OTG_RCLK" to "OTG_REFCLK", net "PS_AVTT" to "PS_MGTRAVTT", and net "PG_DDR" to "PG_DDR1V2".
Type: Schematic Change
Reason: Documentation Improvement
Impact: None.
...
#27 Added testpoints (TP18, TP21
...
... TP25).
Type: Schematic Change
Reason:Improve voltage measuring possibilities Voltage and system monitoring improvement.
Impact: None.
...
#28 Changed signal trace lengths.
Type: PCB Change
Reason: Result of changes above.
Impact: Changed trace length have to be taken into account in existing designs. The trace length for new revision will be available in TE0821 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
...
#29 Updated "FPGA Speed grade" information table on page "TE0821 - POWER".
Type: Documentation Update
Reason: Documentation Improvement
Impact: None.
...
#30 Added power diagram. Updated system overview and revision history. Updated page count and order.
Type: Documentation Update
Reason: Documentation improvementImprovement.
Impact: None.
