Changes

#36 Changed ferrid bead (L1 ... L6) from BKP0603HS121-T to MPZ0603S121HT000.

Type: BOM Change

Reason: EOL of component.

Impact: None.

#36 Swapped clock net name

Type: BOM Change

Reason: EOL of component.

Impact: None.

#1 Changed DCDC EN63A0QI (U7, U14) to LTM4638EY#PBF

Type: Schematic change

Reason: EOL of component.

Impact: None. Maximum continuous output current increased from 12A to 15A per DCDC. 

#7 Changed load switch TPS27082LDDCR (Q1) to MP5077GG-Z and adapted circuit.

Type: Schematic Change

Reason: BOM Optimization.

Impact: None. Minor changes in electrical characteristics.

#7 Added diode (D2) between signals "INIT_B" and "PROG_B".

Type: Schematic Change

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

Impact: None.

#4 Added power supervisor STM6710LWB6F (U21) and connected it to system controller (U18) pin 5 via net "PG_ALL".

Type: Schematic Change

Reason: Improve power monitoring.

Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range signal "PG_ALL" is triggered.

#31 Signal trace lengths changed

Type: PCB change

Reason: Result of changes above.

Impact: Changed trace length have to be taken into account in existing designs. The trace length for new revision will be available in TE0841 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.

#25 Added legal notices, system and power diagram. Updated revision history. Updated page count and order. 

Type: Documentation Update

Reason: Documentation improvement.

Impact: None.
