Part Number: DS250DF230
Hi Team,My customer has DS250DF230EVM and mounted device is DS250DF230 Beta(A0) that REG_F0 is 0x00.I think DS250DF230 Beta(A1) that REG_F0 is 0x01 is new version so could you tell me the difference?Best Regards,Yaita
someone will reply soon

May I have your reply?Best Regards,Yaita
In reply to K.Yaita:
The DS250DFD230 Rev A0 vs A1 designs are nearly identical. There are only three small functional changes in A1 production silicon over A0, as listed below.

Hi Rodrigo-san,Thank you for your kind support.I would like to ask additional questions as following. ------------------------------------------•Improved eye opening margin at extreme high temperature[Yaita] I understand.•Optimization to tighten CDR lock time distribution across PVT[Yaita] What does "PVT" mean?•Added bit control to the Tx output amplitude for when the channel is configured in CDR bypass mode[Yaita] I confirmed programmer's guide page 49 and understand it. Does A0 design fix at default setting (REG_0x1A[7:6] = 1)?------------------------------------------Best Regards,Yaita
PVT stands for "process voltage and temperature"
For A0 version when the retimer is set to CDR bypass mode the output amplitude is fixed and not adjustable; this value is around ~700mVpp.
