Changes
#1 Changed DDR4 SDRAM (U4, U5) from K4A8G165WB-BIRC to K4A8G165WC-BITDTCV.
...
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.
Impact: None.
#8 Added pull-up resistor (R79
...
... R82) for signals "PROG_B", "INIT_B", "DONE", "PG_GT".
Type: Schematic Change
Reason: Use external pull-up resistor.
...
Reason: Increase voltage rating.
Impact: None.
...
#12 Changed 22 µF capacitor (C23, C28, C30, C32, C34) from 6.3 V to 10 V.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#13 Changed 47 µF capacitor (C1, C3 ... C6, C13 ... C15, C60) from 0805 to 0603.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#14 Changed 100 µF capacitor (C61) from 6.3 V, 1206 to 4 V, 0805.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#15 Changed resistor (R35) from 4.7 kOhm 50 mW, 0201 to 2.37 kOhm 63 mW, 0402.
Type: Schematic Change
Reason: Follow AMD recommendation.
Impact: None.
...
#16 Changed resistor (R25, R26, R52, R57) from 4.7 kOhm 50 mW, 0201 to 23.7 kOhm 63 mW, 0402.
Type: Schematic Change
Reason: Decrease current flow through resistor.
Impact: None.
...
#17 Set resistor (R71) to not fitted.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#18 Added testpoint (TP3 ... TP37).
Type: Schematic Change
Reason: Power and signal monitoring improvement.
Impact: None.
...
#19 Swapped clock (U11) net name "CLK200M_P" and "CLK200M_N" at pin 4 and 5.
Type: Schematic Change
Reason:Documentation improvement.
Impact: None.
...
#20 Removed track-it traceability pad S/N.
Type: Schematic Change
Reason: EOL of Component.
Impact: None.
...
#21 Added CE-, UKCA- and RoHS-logo.
Type: PCB Change
Reason: Improve product classification.
Impact: None.
...
#22 Updated components from library.
Type: Schematic Change
Reason: Use latest component data.
Impact: None.
...
#23 Signal trace lengths changed
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 TE0841 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
...
#24 Added legal notices, system and power diagram. Updated revision history. Updated page count and order.
Type: Documentation Update
