General Description

The TriQuint 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 users 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 TGA4959-SL is RoHS compliant. Evaluation boards are

available upon request.

Typical S-Parameters

Vd = 5 V, Idtot = 428 mA,

Vc3 = 0.53 V, Vg2 = -0.9 V, Vg3 = -1.6 V
