TriQuint Semiconductors latest solution addresses the needs of long-haul and ultra-long-distance fiber systems; we are proud to offer the 1^st 32 Gb/s surface-mount technology (SMT) differential modulator driver for optical networks. TriQuint's new product solution offers the lowest power consumption available for a device of this nature: Pdiss of 2.2W at 8Vpp.

The TriQuint TGA4959-SL is a single-chip differential input and output optical Mach Zehnder (MZ) 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 offchip 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 automatically set on-chip 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 the top or bottom edge of the package and the package can be operated with as few as four separate power supplies, if desired.
