Title | TE0803-01 to TE0803-02 Hardware Revision Change |
Subject | Trenz Electronic TE0803 Hardware Change |
Issue Date | 20181214 |
Products Affected
This change affects all variations of TEF1001 SoMs of revision: TEF1001-01-*
affected product | suggested upgrade |
---|---|
TEF1001-01-* | TEF1001-02-* |
Changes
#1 Added C87, C88 4.7µF
Type: Schematic change
Reason: Enhance PL internal supply voltage ripple.
Impact: None
#2 C154 Incremented from 27pF to 33pF
Type: BOM change
Reason: Adjust feed back compensation capacitor of 1.8V DCDC for best performance.
Impact: None
#3 Routed 12V Input from PCIe Edge Connector, Added Input Power Protection Circuits for ATX 12V and PCIe Edge Connector (U23 with T1, T2 and U24 with T5, T6, Resistors and Capacitors), Power Priority Switch T3
Type: Enhancement
Reason: Allow for using PCIe power supply, protect against over and under voltage.
Impact: Card can be supplied by PCIe edge connector (max 25W), but if ATX supply is connected this has priority.
#4 Added 4xDip Switch S1
Type: Schematic change
Reason: Allow for easily selection of FMC VADJ and enable JTAG interface of SC CPLD U5.
Impact: FMC VADJ adjustable to 3.3V, 2.5V, 1.8V, 1.5V ,1.25V , 1.2V, 0.8V via S1-2 to S1-4. System Controller JTAG accesible when S1-1 is on.
#5 Added Transistor T4 and Resistors
Type: Enhancement
Reason: Read the FMC_PRSNT_M2C Value
Impact: System controller is able to evaluate if FMC is present or not.
#6 Added Power Switch U25 and Capacitors
Type: Enhancement
Reason: Possibility to switch the FMC fan.
Impact: FMC fan can be swiched by system controller. In the current system controller design the fan is switched on when FMC is present.
#7 Added 10 x LEDs, D1-D10 and Levelshifter (U11, U21, U22)
Type: Enhancement
Reason: Provide possibility for feedback to user
Impact: 10 user LEDs connected to FPGA logic available.
Method of Identification
The model code and revision number (e.g. TEF1001-01 or TEF1001-02) are printed on the top side of the PCB.
Production Shipment Schedule
After November 2018.
