Clock recovery and data retiming IC — what it is and where it fits
The Maxim Integrated MAX3875AEHJ is a clock recovery and data retiming IC designed to extract a clean clock from a serial data stream and re-time the data edges, reducing jitter and improving signal integrity in high-speed digital links. Typical applications include optical transceivers, backplane serial links, and test equipment where the incoming data lacks a dedicated clock line.
RoHS non-compliant — BOM impact
The MAX3875AEHJ is RoHS non-compliant, which means it contains lead (Pb) or other restricted substances above the RoHS exemption thresholds. This is a hard constraint for designs targeting lead-free assembly per EU RoHS or similar regulations. For legacy or exempt applications (e.g., military, aerospace, or high-reliability systems where leaded solder is still permitted), this part remains a valid choice. If your BOM requires RoHS compliance, a lead-free variant or alternative should be sourced.
