Part Number: DS125DF410

Hello,

I am looking for a CDR to go from the 40Gbase-KR to QSFP+. I was looking at the DS125DF410 but is there a better/newer part I should consider?

Thanks,
Adam

    From TI retimer portfolio the DS125DF410 is still the most suitable alternative for KR to QSFP interfaces. We have newer 25g and 56G retimers. However their CTLE boost profile is optimized at 25gbps Nyquist, while the DS125DF410 CTLE is optimized for 10Gbps.

    Thanks,
