What should we do to configuration this chip before use through I2C interface?

Hi,

By default this device will operate with an input data-rate of 10.3125 or 1.25 Gbps. Are there any other data-rates of interest in your application?

Regards,

Lee

Hi Lee:

We just use the date-rate of 10.3125Gbps.

Hi Lee:

One more question,did this chip support 10G KR ?

Hi,

While the DS110DF111 supports 10.3125 Gbps rates, it does not support 10G-KR due to the requirement for 10G-KR to use out-of-band auto-negotiation and link-training to optimize the link. This process would interrupt the normal CDR lock behavior of the DS110DF111. For 10G-KR support, we recommend using redrivers instead, such as the DS100BR111 or DS125BR111.

Thanks,

Michael
