The TQ8218/TQ8219 is a low jitter, high performance
optoelectronic driver intended for interfacing LVPECL or CML
outputs from a multiplexer or clock recovery device to various O/E
devices, including uncooled DFB lasers, high power VCSEL
arrays, EA modulators and Mach-Zender modulators. The devices’
symmetry and level controls, low additive jitter, and excellent rise/
fall times while driving significant loads allow the highest system
level performance at low cost. The small footprint makes the
devices particularly suitable for high port count WDM applications.
