Qorvo's 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 TGA4954-SL consists of two high performance wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single TGA4954-SL placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution.
The TGA4954-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation (1.1 W at Vo = 6 V), low rail ripple, high voltage drive capability at 5 V bias (6 V amplitude adjustable to 3 V), low output jitter, and low input drive sensitivity (250 mV at Vo = 6V).
The TGA4954-SL requires external DC blocks, a low frequency choke and control circuitry. The part is lead-free and RoHS compliant. Evaluation boards are available upon request.
Typical Applications
- Mach-Zehnder Modulator Drivers
- Metro and Long Haul Optical Networks
