Wide Drive Range (3V to 10V)
•
Single-Ended Input/Output
•
Low Power Dissipation
(1.1W @ 6Vo)
•
Low Rail Ripple
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 compatible with
Metro MSA standards.
The 4954 consists of two high performance
wideband amplifiers combined 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).
