Description
The TriQuint TGA4953-SCC-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 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 (1.1W at Vo = 6V), very low rail ripple,
high voltage drive capability at 5V bias (6 V
amplitude adjustable to 3 V), low output jitter (1ps
rms typical), and low input drive sensitivity (250mV
at Vo = 6V).
The 4953 requires external DC blocks, a low
frequency choke, and control circuitry.
The TGA4953-SCC-SL is available on an evaluation
board.
RoHS compliant version available.
