9.9 - 12.5 Gb/s Optical Modulator Driver
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%)
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.
• Package Dimensions:
11.4 x 8.9 x 2.0 mm
(0.450 x 0.350 x 0.080 inches)
• Mach-Zehnder Modulator Driver
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.
Vdd=5V; Id1=65mA; Id2=115mA; Vctrl1=-0.2V;
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).

The 4954 requires external DC blocks, a low
frequency choke, and control circuitry.
Evaluation boards available upon request.
Lead Free & RoHS compliant.
Note: This device is early in the characterization process prior to finalizing all electrical test specifications. Specifications are subject to
