This change affects all Trenz Electronic TEBF0808 SoMsCarrier: TEBF0808-04A*.
Affected Product | Replacement |
---|---|
TEBF0808-04A | TEBF0808-05 |
...
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#6 Changed
...
DCDCs EN5311QI (U28, U43) to MP2164GG-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
...
Type: Schematic Change
Reason: Follow Follow AMD recommendation.
Impact: Reduced voltage level for signal "PSBATT" from 1.8 V to 1.2 V.
...
Impact: FireFly using custom firmware needs to be adapted by customer.
#10 Changed eMMC (U2) from
...
MTFC4GACAJCN-
...
4M IT to SDINBDG4-8G-XI2.
Type: Schematic change
Reason: EOL of Component.
...
Impact: None. Change voltage level between CPLD voltage rail "3V3SB" and ATX connector voltage rail "5VSB" for signal "PSON". Change logic level for signal "PSON". CPLD firmware reflects it but customer firmware needs to be checked/adapted by customer.
#19 Changed ESD protection diode (U11, U20, U49 ... U51) from ESD3V3U4ULC E6327 to CPDA10R3V3U-HF.
Type: Schematic Change
Reason: EOL of Component.
Impact: None.
#20 Connected all shield signals for connector (J7) together to net "FGND". Removed shield signals (J7) from net "F2GND". Removed capacitor (C261).
...
Reason:EOL of component.
Impact: None.
#37 Changed 33 nF capacitor (
...
C192) from 50 V, 0603 to 25 V, 0402.
Type: Schematic Change
Reason: BOM Optimization.
...
Reason: BOM Optimization.
Impact: None.
...
#45 Changed capacitor (
...
C39, C82, C207) from 4.7 µF
...
Type: Schematic Change
Reason: Decrease battery load.
Impact: None.
#45 Changed capacitor (C39, C82, C207) from 4.7 µF, 6.3 V to 10 µF, 10 V.
Type: Schematic Change
...
Reason: Improve signal integrity for FireFly connector (J6, J21).
Impact: None.
#62
...
Set ferrid bead (L20), capacitor (C127), resistor (R181), LDO TPS79901DRV (U47) and related components
...
to not fitted.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...
#65 Set
...
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
#64 Set capacitor (C127) to not fitted.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
#65 Set capacitor (C16capacitor (C16, C17) to not fitted.
Type: Schematic Change
Reason: Harmonize with TEBF0818 series.
Impact: None.
#66 Set resistor (R181) as not fitted.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
#67 Set resistor (R98, R198) as not fitted.
