Changes
#1 Changed EN63A0QI to MP8869SGL-Z for U14
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. Added testpoint TP25 at signal "PG_ALL".
Type: Schematic Change
Reason: Power Handling Improvement
Impact: Voltages are monitored and if out of range reset is triggered.
#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 Connect U14 to I2C bus via resistors R80 and R81 and pull-up resistors R26 and R27 and testpoints TP23 and TP24.
Type: Schematic Change
Reason: Improvement of DCDC handling.
Impact: None. I2C bus has additional device.
#12 Change SI5338A-B-GM firmware.
- New CBP version (4.6) is used which leads to MultiSynth parameter changes.
- Enable optional FPGA Fabric clock CLK0 100 MHz with LVDS.
- Enable clock CLK1 50 MHz with two single ended (Port A and B) CMOS in phase clocks instead of one (Port A) used for ETH PHY syncronisation.
Type: Firmware Change
Reason: Improved PLL settings.
Impact: Two additional clocks are availabe. Settings are saved in NVM. Minor changes in electrical characteristics.
#13 Added legal notices, project overview, and revision changes. Updated page count and page order.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
Method of Identification
The revision number is printed on the top side of the PCB.
