Changes
#1 Replaced buck converter EN6363QI with MPM3860GQW-Z
Type: Schematic Change
Reason: EOL of Component.
Impact: None, minor changes in electrical characteristic.
#2 Replaced TPS27081ADDCR with MP5077GG-Z
Type: Schematic Change
Reason: Component not recommended for new designs.
Impact: None, increased current capability, minor changes in electrical characteristic.
#3 Replaced LPDDR4 RAM IS43LQ32256A-062BLI with IS43LQ32K01S2A-046BLI
Type: BOM Change
Reason: EOL of Component.
Impact: Size of RAM changed from 1GByte to 4GByte. Trenz reference design reflects the changes.
#4 Replaced SiT8008AI-73-XXS-52.000000E with SiT8008BI-73-XXS-52.000000E
Type: BOM Change
Reason: EOL of Component.
Impact: None.
#5 Added power supervisor BD39040MUF-C
Type: Schematic Change
Reason: Improve power supervision.
Impact: None,
#6 Net PG_FPD replaced by PG_ALL at CPLD
Type: Schematic Change
Reason: Improve power supervision.
Impact: None.
#7 Added MOSFET T2A
Type: Schematic Change
Reason: Result of supervised power rails should be reflected in POR B and PG_ALL, ensures compliance with power-up sequence.
Impact: None.
#8 Added C144 and C145 and optional 100 ohm termination resistor
Type: Schematic Change
Reason: Skyworks AN408 recommends to use AC coupling for LVDS outputs when output driver @1.8V.
Impact: None (LVDS output on CLK0). If customer design implemented a single ended clock, this should be changed to LVDS.
#9 All LVDS and MGT tracks extended by 1 mm due to PCB changes
Type: PCB change
Reason: Due to changes above trace length of nets had to be changed.
Impact: None. Trace length changed, but this is carried out consistent over all IO groups. Therefore relative net length should have been preserved. Please also check online available trace length sheet.
#10 Renamed net PS_LP0V85 to PS_LPVCC and net PS_FP0V85 to PS_FPVCC
Type: Schematic Change
Reason: New names are correct independent from assembly version.
Impact: None.
Method of Identification
The revision number is printed on the top side of the PCB.
Production Shipment Schedule
From March 2026, after old stock is gone. If the new revision is not suitable for your application and still the former revision of the board is needed, please contact us.
