TMS320DM8168: TMS320DM8168

Part Number: TMS320DM8168

Support Path: /myTI & TI store/myTI account/

Dear TI,

i'm Valerio from Italy,i create my custom pcb with DM816x,i use schematics with netra demoboard.I use pcb in 8 layer,which lay up,distance in layer stack up for pcb in 8 layer?

Thanks!

Best regards!

Vale

  • Hi Valerio,

    DM816x TI EVM is designed with 6 layers (2 signals, 2 power, 2 ground). You can re-design your PCB with 8 layers, but you should follow the requirements for controlled impedance for traces (single ended and differential) that this is necessary (example DDR3 routing). You should follow DM816x datasheet impedance requirements (for example see DDR Single-ended impedance, Zo).  You can also refer to the impedance trace of the DM816x TI EVM.

    Regards,

    Pavel

  • Dear Pavel,thanks for help,i try to view in datasheet for impedance requirements in DM816x.I view impedance trace in DM816x TI EVM.Thanks!Best Regards!Vale
