Products Affected

This change affects all Trenz Electronic TEXXXX SoMs: TEXXXX-XX*.

Changes

#1 Changed EN63A0QI to MP8869SGL-Z for U14 and connect it to I2C bus via resistors R80 and R81 and pull-up resistors R26 and R27 and testpoints TP23 and TP24.

Type: Schematic Change

Reason: EOL of Component

Impact: None. Minor changes in electrical characteristics.

#2 Changed EP53F8QI to MPM3834CGPA for U6 and U16.

Type: Schematic Change

Reason: EOL of Component

Impact: None. Minor changes in electrical characteristics.

#3 Changed power switch TPS27082LDDCR to MP5077GG-Z for Q1.

Type: Schematic Change

Reason: EOL of Component

Impact: None. Minor changes in electrical characteristics.

#4 Added power monitors STM6710LWB6F (U10, U11). Changed system controller pin 25 from 3.3V to signal "PG_ALL" from new power monitors. Add testpoint TP25 at signal "PG_ALL".

Type: Schematic Change

Reason: Power Handling Improvement

Impact: None. Voltage supply monitoring leads to resets.

#5 Added diode D3 between signals "INIT" and "PROG_B".

Type: Schematic Change

Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.

Impact: None.

#6 Change resistor values for R2 and R68 from 4.87 kOhm to 2.2 kOhm.

Type: Schematic Change

Reason: Improve I2C stability for higher baud rates.

Impact: None. I2C stability improvement.

#7 Change resistor values for R62 from 2.49 kOhm to 4.99 kOhm and for R63 from 4.99 kOhm to 10 kOhm.

Type: BOM Change

Reason: BOM Optimization.

Impact: None. Minor changes in electrical characteristics for DCDC U8.

#8 Change capacitors in net "VIN" from 47 uF 6.3 V to 22 uF 10 V for C70, C80, C126, C127, C132, C176, C177.

Type: Schematic Change

Reason: Improve reliability.

Impact: None. Minor changes in electrical characteristics.

#9 Change capacitors C18, C19, C125, C158, C174.

Type: Schematic Change

Reason: BOM Optimization.

Impact: None. Minor changes in electrical characteristics.

#10 Change ferrid beads BKP0603HS121-T to MPZ0603S121HT000 for L1, L2, L3, and L5.

Type: Schematic Change

Reason: EOL of component.

Impact: None. I2C stability improvement.

#11 Change SI5338A-B-GM programming settings.

Type: Schematic Change

Reason: Unify settings.

Impact: None. Minor changes in electrical characteristics.

#12 Added legal notices, project overview, and revision changes. Updated page count and page order.

Type: Documentation Update

Reason: Documentation improvement.

Impact: None.
