Type: Schematic Change
Reason: BOM OptimizationEOL of Component
Impact: None. Minor changes in electrical characteristics.
...
Type: Schematic Change
Reason: BOM OptimizationEOL of Component
Impact: None. Minor changes in electrical characteristics.
...
Type: Schematic Change
Reason: Follow Updated decoupling capacitor structure according to Xilinx recommendations.
Impact: None. Minor changes in electrical characteristics.
#5 Insert DDR4 testing option (R116, TP9).
Type: Schematic Change
Reason: Allow extended automatic DDR4 testing.
Impact: None.
...
Reason: Power management improvement.
Impact: None. All power supplies are monitored.
#8 Changed SiT8008AI-73-XXS-52.000000E to SiT8008BI-73-XXS-52.000000E for U14.
...
Reason: Improve power management.
Impact: None.
#9 Changed reset, enable and power-up structure with resistor R95, added transistor T2, and added resistor R128.
Type: Schematic Change
Reason: Improve module reset, enable, and power-up.
Impact: Changed Module reset, enable, and power-up handling . Pleaseis modified. That means that "EN1" signal from B2B connector enables DCDC U5 and can be monitored by CPLD U21 pin 27 (assembly option) (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 standard. Therefore, please, verify that the module meets your requierements.
...
Reason: Connect both PHY signals to SoC.
Impact: None. Signal optional available at SoC (assembly option).
#11 Added resistors R130 and R131 to add pull-up/-down option for SoC "POR_OVERRIDE" signal.
...
Reason: Improvement to allow "POR_OVERRIDE" state change.
Impact: None. Assembly option with power override possible.
#12 Added diode D5 to protect manual reset input signal.
...
Type: Schematic Change
Reason: Improve Change reset voltage threshold from 0.74 V to 0.775 V.
Impact: None. Improve brown-out detection.
#15 Added resistor R132 as assembly option.
...
Reason: R92 is not needed.
Impact: None. Not needed for x16 DDR4.
#17 Added power diagram page.
