Claim 18:
19. A system for Vertical-Cavity Surface-Emitting Lasers (VCSELs) binning, the system comprising:
a VCSEL stimulator that applies a stimulus to at least some VCSELs on a wafer;
a VCSEL measurement unit that measures two or more VCSEL parameters responsive to the stimulus;
a processor; and
memory coupled with the processor that comprises instructions which, when executed by the processor, enable the processor to:
for the at least some VCSELs, measure a set of representative parameters of the VCSELs and sort the measured VCSELs into clusters according to the measured set of representative parameters of the VCSELs;
match between an input impedance and an output impedance of the VCSELs and a VCSEL driver;
sort the clusters into sub-groups based on the matching to that comply with specifications of the VCSEL driver; and
provide a feedback signal to a Clock Data Recovery Unit (CDRU) for equalizing control signals provided to the VCSEL driver.
