The TriQuint TGA4953-EPU 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 4953 consists of two high performance wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single 4953 placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution. The 4953 provides Metro and Long Haul designers with system critical features such as: low power dissipation (1.1 W at Vo=6 V), very low rail ripple, high voltage drive capability at 5V bias (6 V amplitude adjustable to 3 V), low output jitter (10 ps typical), and low input drive sensitivity (250 mV at Vo=6 V).
