Type: Schematic Change
Reason: EOL of Component
Impact: None. Minor changes in electrical characteristics.
Type: Schematic Change
Reason: BOM Optimization
Impact: None. Minor changes in electrical characteristics.
Type: Schematic Change
Reason: EOL of Component
Impact: None. Minor changes in electrical characteristics.
Type: Schematic Change
Reason: Updated decoupling capacitor structure according to Xilinx recommendations.
Impact: None.
Type: Schematic Change
Reason: Allow extended automatic DDR4 testing.
Impact: None.
Type: Schematic Change
Reason: BOM Optimization
Impact: None. Minor changes in electrical characteristics.
Type: Schematic Change
Reason: Power management improvement.
Impact: None. All power supplies are monitored.
Type: Schematic Change
Reason: Improve power management.
Impact: None.
Type: Schematic Change
Reason: Improve module reset, enable, and power-up.
Impact: Module reset, enable, and power-up handling is modified. That means that "EN1" signal from B2B connector enables DCDC U5 and can be monitored by CPLD U21 pin 27 (backward compatible mode with assembled resistor R95 and signal "EN1" as enable input), or that signal "EN1" only enables DCDC U5 and CPLD U21 pin 27 is connected to signal "POR_B" via voltage translator T2 (normal mode). Normal mode is the standard. Therefore, please, verify carefully which module meets your requierements and order the correct one.
Type: Schematic Change
Reason: Connect both PHY signals to SoC.
Impact: None. Signal optional available at SoC (assembly option).
Type: Schematic Change
Reason: Improvement to allow "POR_OVERRIDE" state change.
Impact: None. Assembly option with power override possible.
Type: Schematic Change
Reason: Improvement to protect reset input signal.
Impact: None.
Type: Schematic Change
Reason: Use latest component data.
Impact: None.
Type: Schematic Change
Reason: Change reset voltage threshold from 0.74 V to 0.775 V.
Impact: None. Improve brown-out detection.
Type: Schematic Change
Reason: Added assembly option for DCI.
Impact: None.
Type: BOM Change
Reason: R92 is not needed.
Impact: None. Not needed for x16 DDR4.
Type: Documentation Update
Reason: Power documentation improvement.
Impact: None.
