TGA4959-SL
32 Gb/s Optical Modulator Driver with Differential Input & Output
Qorvo's TGA4959-SL is a differential input and output optical modulator driver designed to operate at frequencies that target the 40 Gb/s optical market. The TGA4959-SL consists of a wideband amplifier assembled in a surface mount package combined with a minimum of external components. A single TGA4959-SL placed between the MUX and Optical Modulator provides OEMs with a differential modulator driver surface mount solution.
The TGA4959-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, low rail ripple, high voltage drive capability (6 Vpp amplitude adjustable up to 9 Vpp) and very low output jitter.
Several of the bias pins on the TGA4959-SL are internally set to simplify the user's PCB design. Alternatively, these same pins can be adjusted by the user, if desired. Duplicate pins are available to enable biasing from either side of the package and the package can be operated with as few as four separate power supplies, if desired. The part is RoHS compliant. Evaluation boards are available upon request.
