Dear Customer,
Thank you for being interested in our CDR products.
AD807 is one 5V, narrow band CDR. Its capture/tracking ranges are both from 155MHz to 156MHz.
To support a 50MHz or 50Mbps data stream CDR function, we have plenty CDRs.
Both ADN2816 or ADN2813 might be a good candidate for your target applications.
Please get on our public website: www.analog.com and type in the product number to browse
the CDR datasheets. Hope this suggestion is useful to you.
Best Regards,
Dongfeng Zhao
