9.9 - 12.5 Gb/s Optical Modulator Driver
TGA4954-SL
Key Features and Performance
• Wide Drive Range (3V to 10V)
• Single-Ended Input/Output
• Low Power Dissipation
(1.1W @ 6Vo)
• Low Rail Ripple
• 25psec Edge Rates (20/80%)
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 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 (1.1W 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).
• Hot-pluggable
• Package Dimensions:
11.4 x 8.9 x 2.0 mm
(0.450 x 0.350 x 0.080 inches)
Primary Applications
• Mach-Zehnder Modulator Driver
