Product Description

The TriQuint TGA4954-SL is part of a series of

surface mount modulator drivers suitable for a

variety of driver applications and is compatible with

Metro MSA standards.

The 4954 consists of two high performance

wideband amplifiers combined with off chip circuitry

assembled in a surface mount package. A single

4954 placed between the MUX and Optical

Modulator provides OEMs with a board level

modulator driver surface mount solution.

The 4954 provides Metro and Long Haul designers

with system critical features such as: low power

dissipation (1.2W at Vo = 6V), low rail ripple, high

voltage drive capability at 5V bias (6 V amplitude

adjustable to 3 V), low output jitter, and low input

drive sensitivity (250mV at Vo = 6V).

The 4954 requires external DC blocks, a low

frequency choke, and control circuitry.

Evaluation boards available upon request.

Lead Free & RoHS compliant.

Note: This device is early in the characterization process prior to finalizing all electrical test specifications. Specifications are subject to

change without notice.
