Changes
#1 Changed DCDCs from TPS82085SIL to MPM3834CGPA-Z for U1 and U19.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#2 Changed DCDC from EP5357HUI to MPM3834CGPA for U3.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#3 Changed TPS27081ADDCR to MP5077GG-Z for Q1.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#4 Changed voltage monitor TPS3805H33DCKR to STM6710LWB6F for U23 and added resistor R38.
Type: Schematic Change
Reason: BOM Optimization.
Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range reset is triggered.
#5 Added diode D2 between signals "INIT" and "PROG_BD".
Type: Schematic Change
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.
Impact: None.
#6 Changed inductors from BKP0603HS121-T to MPZ0603S121HT000 for L1, L2, L10, and L11.
Type: Schematic Change
Reason:EOL of component.
Impact: None.
#7 Added voltage translator for signal "EN_GTPWR" (U10, C34, R36, R46).
Type: Schematic Change
Reason: Improve clock enable signal.
Impact: Set proper signal voltage.
#8 Changed power sequence for U5 and U6.
Type: Schematic Change
Reason: Use recommended power sequence.
Impact: None.
#9 Changed voltage rail 1.35V_LDO to 1.4V_LDO and increased voltage accodingly.
Type: Schematic Change
Reason: Improve voltage rail behaviour.
Impact: None.
#10 Updated decoupling capacitors (added C43...46, C53, C60).
Type: Schematic Change
Reason: Improve decoupling according to Xilinx recommendation.
Impact: None.
#11 Removed serial number S/N and used FPGA U4 pins H14, D10,R6, J6 for PCB REV identification.
Type: Schematic Change
Reason: EOL of component.
Impact: Check that these FPGA pins are handled properly.
#12 Added testpoints for 1.0V (TP17 and TP18) and for SENSE net (TP19 and TP20).
Type: Schematic Change
Reason: Improved debugging possibilities.
Impact: None.
#13 Added pull-up resistor R37 and testpoint TP21 for DCDC U6 PG pin.
Type: Schematic Change
Reason: Improved debugging possibilities.
Impact: None.
#14 Added testpoints TP10...16 on top layer.
Type: Schematic Change
Reason: Improved debugging possibilities.
Impact: None.
#15 Added UKCA logo.
Type: PCB Change
Reason: Requiered for export to UK.
Impact: None.
#15 Added RoHS logo.
Type: PCB Change
Reason: Documentation Improvement.
Impact: None.
#16 Added system overview, power diagram, and legal notices.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.Impact:
