Impact: None.
#11 Changed connection for resistors R4 and R5 from power net to GND net and changed standard assembly status to fitted.
Type: Schematic Change
Reason: Follow Display Port Standard.
Impact: None.
#12 Changed net name SOURCEDP_PWRCON to SOURCEDP_CONFIG2 and added assembly option to connect Config2 source side to GND (R72).
Type: Schematic Change
Reason: Follow Display Port Standard.
Impact: None.
#13 Renamed net "PG_0V85" to net "PG_1V0".
Type: Schematic Change
Reason: Correct voltage level in name according to voltage rail level.
Impact: None.
#14 Changed resistors R31 and R41 to 330 Ohm.
Type: BOM Change
Reason: Decrease LED brightness.
Impact: None.
#15 Changed voltage rating from 16 V to 100 V and size from 0402 to 1206 for capacitor (C14, C48).
Type: Schematic Change
Reason: Improve capacitors characteristics for capacitor functionality.
Impact: None. Improved characteristics.
#16 Added testpoints TP5...TP14 and TP16...TP20.
Type: Schematic Change
Reason: Improve testability.
Impact: None.
#17 Length matched all differential signals smaller than 0.1 mm.
Type: PCB Change
Reason: Improve signal integrity.
Impact: None. Minor trace length change. The trace length for new revision will be available in TEF0007 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
