TE0706-03#1 ... #25TE0706-04-A
TE0706-03-D#2 ... #25TE0706-04-B

Changes

#1 Changed resistor (R39) from not fitted to fitted.

Type: BOM Change

Reason: Do not allow floating signal "OTG_ID".

Impact: None.

#2 Changed DCDC EN6347QI (U1) to MPM3860GQW-Z and adapted power circuit.

Type: Schematic Change

Reason: EOL of Component.

Impact: None. Increased output current capability. Minor changes in electrical characteristics.

#3 Changed DCDC EN5311QI (U3) to MPM3834CGPA-Z and adapted power circuit.

Type: Schematic Change

Reason: EOL of Component.

Impact: None. Increased output current capability. Minor changes in electrical characteristics.

#4 Changed load switch TPS27081ADDCR (Q1) to MP5077GG-Z and adapted circuit.

Type: Schematic Change

Reason: BOM Optimization.

Impact: None. Increased current output capability. Minor changes in electrical characteristics.

#5 Changed SD Card connector (J4) from 504077-1891 to 104031-0811.

Type: Schematic Change

Reason: EOL of Component.

Impact: Mechanical component size increased.

#6 Changed ETH PHY (U6) power supply to use internal LDOs.

Type: Schematic Change

Reason: Follow Marvell recommendation.

Impact: None.

#7 Added ESD protection diode (D1, D2) for USB.

Type: Schematic Change

Reason: ESD Protection.

Impact: None. Added ESD protection.

#8 Added series resistor (R27) for ETH PHY clock signal.

Type: Schematic Change

Reason: Improve signal integrity.

Impact: None.

#9 Added series termination resistor (R50 ... R55) for SDIO signals.

Type: Schematic Change

Reason: Improve signal integrity.

Impact: None.

#10 Added pull-up resistor (R57) to signal "RESIN".

Type: Schematic Change

Reason: Harmonize "RESIN" signal handling.

Impact: None. Module internal pull-up resistor for signal "RESIN" is not needed anymore.

#11 Connected signal "PGOOD" to DIP switch S1 and pulled it up to voltage rail 3.3V via resistor (R56).

Type: Schematic Change

Reason: Enable boot mode JTAG-only for Zynq modules.

Impact: JTAG-only boot mode can be selected with DIP switch S1 for Zynq modules.

#12 Changed ferrid bead (L3, L5) from BKP0603HS121-T to MPZ0603S121HT000.

Type: BOM Change

Reason: EOL of component.

Impact: None.

#13 Changed pin header (J9) from SMD to THT.

Type: Schematic Change

Reason: Improve manufacturing process.

Impact: None.

#14 Changed pin header (J10 ... J13) from SMD to THT.

Type: Schematic Change

Reason: Improve manufacturing process.

Impact: None.

#15 Added testpoint (TP1 ... TP9).

Type: Schematic Change

Reason: Voltage and system monitoring improvement.

Impact: None.

#16 Renamed power rail name from "VCCIOC" to "VCCIOD".

Type: Schematic Change

Reason: Follow Trenz module connection table.

Impact: None.

#17 Renamed power rail name from "VCCIOB" to "VCCIOC".

Type: Schematic Change

Reason: Follow Trenz module connection table.

Impact: None.

Type: Schematic Change

Reason: EOL of Component.

Impact: None.

#19 Changed fiducials to standard fiducial type.

Type: Schematic Change

Reason: Use standard fiducials.

Impact: None.

#20 Updated Trenz address.

Type: PCB Change

Reason: Update address.

Impact: None.

#21 Added UKCA- and RoHS-logo.

Type: PCB Change

Reason: Improve product classification.

Impact: None.

#22 Updated components from library.

Type: Schematic Change

Reason: Use latest component data.

Impact: None.

#23 Added legal notices, block and power diagram. Updated revision history. Updated page count and order. 

Type: Documentation Update

Reason: Documentation improvement.

Impact: None.
