Description
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).
The 4953 requires external DC blocks, a low frequency
choke, and control circuitry.
The TGA4953-EPU is available on an evaluation board.
