HI Sir

Do you have initial reference code of DS125DF1610 ?

It can be easy for our S/W engineer to design DS125DF1610

Thanks

Hi Kai,

What datarates will the DS125DF1610 be working on in this application? We can help to provide register configuration values and sequences based on this information.

Regards,

Lee

HI Lee

1.25Gbps datarate

Do you have document have describe how to set 0x2F

Thanks

Hi Kai,

To program 0x2F for 1.25 Gbps use the table to change the value in bits [7:4].

HI Lee

So you mean ,if i set 0xB in 0x2F register ,DS125DF1610 can support both of 10.3125Gbps and 1.25Gbps ,is it right ?

Thanks

Hi Kai,

The hex code 0xB is for the upper four bits in the register. The lower four bits have a default value of 0x6.

All eight bits in register 0x2F = B6

With this value in register 0x2F the DS125DF1610 will support 10.3125 Gbps and 1.25 Gbps.

Lee

HI Lee

If i would like to use 1.25Gbps ,only 0x2F need to modify
Have any other register need to modify
If you have the programming guide ,it will be better
