DS125DF111: DS125DF111

Part Number: DS125DF111

Hi TI experts

I know this is probably a stupid question, but I am unable to find a register which indicates exactly what rate and sub-rate the DS125DF111 has locked to.

The device is successfully working at both 10.3125GbE rate and 1GbE (sub rate), using the following register settings.

rate & sub-rate 8,1          10G & 1Gb

Reg 0x2F, 0x06                                                

SET rate                                10.0Gb & 10.3125Gb                      

Reg 0x60, 0x00                 

Reg 0x61, 0xB2                 

Reg 0x62, 0x90 

Reg 0x63, 0xB3 

Reg 0x64, 0xCD

 

Register 0x02 indicates the DF125DF111 is locked.

However, without knowing the source, how can I detect which rate and sub-rate the DS125DF111 has locked too?

 

Regards

Cameron

    Hi Cameron,

    This is a good question and I didn't see in our programming guide how to interrogate device registers to show locked data rate - or VCO divisor settings. We just created an FAQ to address this. Please let us know if there is a question/comment:
