Recommended/Default settings for the Si5345

By default Si5345 is not programmed after power on, so if FSBL is executed without proper Si5345 init or if psu_init.tcl is invoked and the design does use PS GT, then FSBL or psu_init.tcl would freeze on SERDES init code. Si5345 init does persist over reset sequence so it is possible to use known good boot files to init Si5345 and then FSBL debugging is also possible.

 

FMC Slot

FMC Slot is fitted as full FMC HPC.

Note: FMC VADJ maximum voltage is 1.8V (as HP banks do not support more than 1.8V).

Optional FAN can be mounted below the FMC slot. Ther are no components below the FMC card, so FMC cards with extended component heights can be used.

Do not scan bus 8, this would cause the I2C bus multiplexer to freeze until power off or hardware reset.

DIP Switches

There are two 4 bit DIP Switches on the TEBF0808, they must be used to select some options. On TEBF0808-02 default CPLD-Firmware selects boot from SD-Card, Firmware update is needed for Boot-Mode selection.
