Changes
#1 Changed DDR3L SDRAM (U12) from IM4G08D3FABG-125 to IS43TR85120BL-125KBLI.
Type: BOM change
Reason: EOL of Component.
Impact: New timings may be considered for existing designs.
#2 Changed DCDC EN6347QI (U1) 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.
#3 Changed DCDC EN5311QI (U10, U11) to MPM3834CGPA and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#4 Changed load switch from TPS27082LDDCR (Q1) 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 power supervisor TPS3805H33DCKR (U23) 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.
#6 Improved voltage rail VTT decoupling via adding capacitors C135...C138.
Type: Schematic Change
Reason: VTT decoupling improvement.
Impact: Improved VTT voltage rail reliabililty.
#7 Changed clock (U9) from SiT8008AI-73-XXS-25.000000E to SiT8008BI-73-XXS-25.000000E.
Type: Schematic Change
Reason: Use new clock revision.
Impact: None.
#8 Changed ferrid bead BKP0603HS121-T (L1...L6) to MPZ0603S121HT000.
Type: Schematic Change
Reason: EOL of Component.
Impact: None.
#9 Added diode D4 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.
#10 Added pull-up resistor R50 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.
#11 Added testpoints TP1...TP28.
Type: Schematic Change
Reason: Improve voltage measuring possibilities.
Impact: None.
#12 Changed size from 0805 to 0603 for capacitor C44.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
#13 Changed fiducials to standard fiducial type.
Type: Schematic Change
Reason: Use standard fiducials.
Impact: None.
#14 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 TE0710 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
#15 Added UKCA logo.
Type: PCB Change
Reason: Required for export to UK.
Impact: None.
#16 Updated components from library.
Type: Schematic Change
Reason: Use latest component data.
Impact: None.
#17 Updated documentation on page "B2B_Connectors".
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
#18 Updated overview, power overview, revision history and legal notices.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
