Changes
#1 Changed DCDC (U1) from EN6347QI 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.
#2 Changed DCDC (U11) from EN5311QI to MPM3834CGPA and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#3 Changed power supervisor (U23) from TPS3805H33DCKR to STM6710LWB6F and adapted circuits.
Type: Schematic Change
Reason: Improved power monitoring.
Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range signal "PG_ALL" is triggered.
#4 Changed load switch (Q1) from TPS27082LDDCR to MP5077GG-Z and adapted circuit.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#5 Changed clock (U6) from SiT8008AI-73-XXS-12.000000E to SiT8008BI-73-XXS-12.000000E.
Type: Schematic Change
Reason: Use new clock revision.
Impact: None.
#6 Added diode (D5) between signal nets "INIT" and "PROG_B".
Type: Schematic Change
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.
Impact: None.
#7 Added pull-up resistor R25 for signal net "PROG_B".
Type: Schematic Change
Reason: Remove floating signal situations and enable signal measurement.
Impact: None. Firmware reflects it but custom firmware needs to be updated by customer.
#8 Changed ferrid bead BKP0603HS121-T (L1...L6) to MPZ0603S121HT000.
Type: Schematic Change
Reason: EOL of Component.
Impact: None.
#9 Changed resistor (R15) from 2.2 kOhm to 470 Ohm.
Type: Schematic Change
Reason: Follow AMD recommendation.
Impact: None.
#10 Added pull-up resistor (R22) for clock U3 enable signal.
Type: Schematic Change
Reason: Follow clock enable recommendation.
Impact: None.
#11 Changed fiducials to standard fiducial type.
Type: Schematic Change
Reason: Use standard fiducials.
Impact: None.
#12 Added serial number box (Serial).
Type: Schematic Change
Reason: Production improvement.
Impact: None.
#13 Added testpoints (TP1...TP19).
Type: PCB Change
Reason: Improve voltage monitoring and signal monitoring.
Impact: None.
#14 Changed CE logo position.
Type: PCB Change
Reason: Result of changes above.
Impact: None.
#15 Added UKCA logo.
Type: PCB Change
Reason: Required for export to UK.
Impact: None.
#16 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 4x5 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
#17 Updated components from library.
Type: Schematic Change
Reason: Use latest component data.
Impact: None.
#18 Updated group tables and colours on "B2B_Connector" page.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
#19 Updated legal notices, revision history, block and power diagram. Updated page count and order.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
