Key Features and Performance
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 patible with Metro MSA standards. The 4954 consists of two high performance .. wideband amplifiers bined 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 pliant.
