TE0835-01-* | TE0835-02-* |
Type: Schematic change
Reason: Some I/O standards with DCI need external VRP.
Impact: DCI I/O standarts with external VRP usable on this bank.
Type: Schematic change
Reason: Primilary installed LDO had disadvantegous output discarge function, which prevents external sourcing of 3.3V_CPLD rail.
Impact: External sourcing of 3.3V_CPLD rail possible.
Type: Schematic change
Reason: Improve routing/signal integrity.
Impact: Signal DBG_LED3 is connected on AD18 pin of FPGA, was AE18.
Type: Schematic change
Reason: Improve routing/signal integrity.
Impact: Signal FPGA_IO0 to CPLD now available at Pin AE18, was AF17.
Type: Schematic change
Reason: PS periphery controller with fixed IO assignments may need MIO13 (e.g. for eMMC).
Impact: MIO13 now availabe at B2B J1, if still MIO25 is needed a jumper resistor has to moved from R76 to R84.
Type: Schematic change
Reason: MIO13 is now user IO.
Impact: No pullup on MIO13.
Type: PCB change
Reason: MIO13 is now user IO.
Impact: It is no more possible to control LED D1 via MIO13.
Type: Schematic change
Reason: Improve solution for enabling CPLD JTAG.
Impact: CPLD update possible when JTAG enabled via shortcut of THT testpoints, also installation of pinheader with jumper possible.
Type: Schematic change
Reason: Inconsistent net naming.
Impact: Nets named according to resident Bank.
Type: BOM change
Reason: Compensation of U7 did not work.
Impact: U7 stable working.
Type: PCB change
Reason: Lenght matching required.
Impact: Clks correctly length matched.
Type: PCB change
Reason: BIAS routed to wrong Powerrail.
Impact: U8 working correctly.
Type: Schematic change
Reason: PGOOD did not work.
Impact: PGOOD of U7 works correct.
The revision number is printed on the top side of the PCB.
The new revison 02 is available from August 2020.
