TQ8319

The TQ8318/TQ8319 is a low jitter, high performance electro-optic driver intended for directly interfacing CML outputs from a multiplexer or clock recovery device to various EO devices, including cooled and uncooled DFB and FP lasers, high power VCSEL arrays, EA modulators and differential Mach- Zehnder (MZ) modulators. The TQ8318 and the TriQuint TGA1328/8652 can be used in combination for single ended 9V MZ drive applications. The TQ8319's 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 TQ8319 also include an offset control to allow adjustment of DC bias between 0V and -1V for EAM/EML, or 0-40mA for laser threshold, applications. The 28 pin TSSOP footprint and low jitter makes the devices particularly suitable for high port count WDM circuit packs and modules, and for optical modules. These TQ8319 are compatible with CMOS, SiGe or GaAs muxes with CML, eLVDS, or LVPECL outputs.
