Changes
#1 Changed DCDC MUN3CAD03-SE (U13, U15, U16, U19, U20, U23, U24, U29, U30, U31 (variant dependent)) to TPS82085SIL and adapted voltage divider resistors.
Type: BOM Change
Reason: TPS82085SIL availability.
Impact: Minor changes in electrical characteristics.
#2 Changed DDR4 SDRAM from NT5AD256M16D4-HR (512 MByte) to K4A8G165WC-BITDTCV (1 GByte).
Type: Schematic Change
Reason: EOL of Component.
Impact: Increased DDR4 memory.
#3 Changed DCDC EN6347QI (U11) to MPM3860GQW-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#4 Connected DDR4-TEN signals together for U2, U3, U9, and U12 and pulled them low via 499 Ohm resistor R131. Added testpoint TP3 for signal DDR4-TEN.
Type: Schematic Change
Reason: Possible test improvement.
Impact: None.
#5 Increased voltage from 1.35 V to 1.45 V via voltage divider resistors (R33 and R38) and changed voltage rail name accordingly from PL_GT_1V35 to PL_GT_1V45.
Type: Schematic Change
Reason: Improve voltage rail behaviour.
Impact: None.
#6 Increased voltage from 1.05 V to 1.15 V via voltage divider resistors (R44 and R46) and changed voltage rail name accordingly from PL_GT_1V05 to PL_GT_1V15.
Type: Schematic Change
Reason: Improve voltage rail behaviour.
Impact: None.
#7 Added diode D2 between U41 pin 3 net MR and voltage rail 3.3VIN to protect manual reset input signal.
Type: Schematic Change
Reason: Protect reset input signal.
Impact: None.
#8 Connected enable signal for DCDCs U11 and U33 from "3.3VIN" to "PG_PL_VCCINT".
Type: Schematic Change
Reason: Updated power sequence according to AMD recommendation.
Impact: None. Updated power sequence.
#9 Improved voltage rail VTT layout and added decoupling capacitors C137, C147, and C148.
Type: Schematic Change
Reason: VTT layout and decoupling improvement.
Impact: Reliable VTT voltage rail.
#10 Added DCDC (U4) VCC supply option via resistors R132 (Default: not fitted) for voltage rail PL_DCIN and R133 (Default: fitted) for voltage rail 3.3VIN.
Type: Schematic Change
Reason: Efficiency improvement for DCDC.
Impact: None. Dependent on used voltage at PL_DCIN the efficiency could be affected.
#11 Change current limit to approximately 14.5 A for DCDC MPQ8633BGLE-Z (U4) via changing resistor R92 from 4.22 kOhm to 9.09 kOhm.
Type: Schematic Change
Reason: Fixed wrong resistor value.
Impact: None.
#12 Added option to use remote senses for DCDCs U30 via resistor R134, U29 via resistor R135 and U31 via resistor R136. These options are not used in default variants.
Type: Schematic Change
Reason: Remote sense option.
Impact: None.
#13 Added additional decoupling capacitors C149...C157, C170...C172, C178, C187...C191, C195...C216.
Type: Schematic Change
Reason: Improve decoupling.
Impact: None.
#14 Added testpoints TP4, TP19, TP26.
Type: Schematic Change
Reason: Improve voltage measuring possibilities.
Impact: None.
#15 Added UKCA logo.
Type: PCB Change
Reason: Requiered for export to UK.
Impact: None.
#16 Changed 100 nF capacitors C135 and C136 from 6.3 V to 25 V.
Type: BOM Change
Reason: BOM Optimization.
Impact: None.
