Changes
#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.
#2 Increased voltage from 1.35 V to 1.42 V via voltage divider resistor (R11) and changed voltage rail name accordingly from PL_GT_1V35 to PL_GT_1V42.
Type: Schematic Change
Reason: Improve voltage rail behaviour.
Impact: None.
#3 Changed load switch TPS27082LDDCR (Q1) to MP5077GG-Z and adapted circuit.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#4 Changed clock (U11) from DSC1123DL5-200.0000 to SIT9121AI-2B1-XXE-200.00000
...
.
Type: Schematic Change
Reason: BOM Optimization.
Impact: Decreased stability from ± 10 ppm to ± 20 ppm. Decreased temperature range from (-40 °C to 105 °C) to (-40 °C to 85 °C). Increased mechanical size.
#5 Added power supervisor STM6710LWB6F (U21) and connected it to system controller (U18) pin 5 via net "PG_ALL" which is pulled-up to power rail "3.3VIN" with resistor (R83).
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.
#6 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.
#7 Added pull-up resistor (R79, R80, R81, R82) for signals "PROG_B", "INIT_B", "DONE", "PG_GT".
Type: Schematic Change
Reason: Use external pull-up resistor.
Impact: None.
#8 Added additional decoupling capacitor (C70 ... C84, C89).
Type: Schematic Change
Reason: Improve power supply.
Impact: None.
#9
17) All SCH symbols and PCB footprints were updated from libruary
18) @{"Id":"DCAOQXUV\DXJIAUUX","ObjectType":2} was changed from 110k to 124k, net "PL_GT_1V35" was renamed to "PL_GT_1V42"
19) @{"Id":"EPHSAIGN\YARQSJWM","ObjectType":2} setted as "DNP"
Changes
