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)
V_OUT = 6 V_PP, CPC = 50%, V_IN = 500 mV_PP
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.
