5GHz (or more) VCSEL Linear Driver for High Modulation Formats

Hello Team,

My application require to drive VCSEL with high modulation format (e.g. PAM-4, 5GBps = 10 Gpbs). Hence, I need a linear laser driver to modulate the VCSEL with several level of power outputs.

Can ADN2531 support such modulation formats? If not, can you suggest other linear laser drivers with 5GHz bandwidth (or more)? 

With Thanks and Regards,

Itay
