DS125DF410: Estimation of received data rate

child sun

Part Number: DS125DF410

Hi TI Team,

Could you let us know how to estimate/measure (by using the chip's functions) the data rates of the signals as seen by the inputs of the chip? Let's assume that the incoming signals are all locked by the CDRs.

Thanks.

Hi Child,

I am not aware of any method through which the data rate of a signal could be measured using the retimer. Typically, if the CDR can be locked to the incoming data, this indicates that the data rate is either the rate set in group 0 / 1 or a subrate of this. However, I am not aware of any status registers indicating the group or divider that is being used to lock to the signal.

Thanks,

Drew
