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.

Applications

• VCSEL driver

• Driving uncooled DFB lasers

• Single-ended 50Ω 4.0V

electro-absorptive modulator
