9.9-12.5Gb/s Optical Modulator Driver

TGA4953-SL

OC-192 Metro and Long Haul Applications

Surface Mount Package

Key Features and Performance

• Metro MSA Compatible

• Wide Drive Range (3V to 10V)

• Single-ended Input / Output

• Low Power Dissipation

(1.1W at Vo = 6V)

• Very Low Rail Ripple

• 25ps Edge Rates (20/80)

• Small Form Factor

- 11.4 x 8.9 x 2 mm

Description

- 0.450 x 0.350 x 0.080 inches

The TriQuint TGA4953-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 TGA4953-SL consists of two high performance

wideband amplifiers combined with off chip circuitry

assembled in a surface mount package. A single

TGA4953-SL placed between the MUX and Optical

Modulator provides OEMs with a board level

modulator driver surface mount solution.

The TGA4953-SL 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).

Primary Applications

• Mach-Zehnder Modulator Driver for

Metro and Long Haul

• IRZ & Duobinary Applications

Measured Performance

TGA4953-SL Evaluation Board (Metro MSA Conditions)

10.7 Gb/s, Vdd = 5 V, Idd = 210 mA, (Pdc = 1.1W)

VOUT = 6 VPP, CPC = 50%, VIN = 500 mVPP

Scale: 2 V/div, 15 ps/div

The TGA4953-SL requires external DC blocks, a

low frequency choke, and control circuitry.

The TGA4953-SL is available on an evaluation

board.

RoHS compliant version available.
