Description
The TriQuint TGA4953-EPU 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 4953 consists of two high performance wideband
amplifiers combined with off chip circuitry assembled in a
surface mount package. A single 4953 placed between
the MUX and Optical Modulator provides OEMs with a
board level modulator driver surface mount solution.
The 4953 provides Metro and Long Haul designers with
system critical features such as: low power dissipation
(1.1 W at Vo=6 V), very low rail ripple, high voltage drive
capability at 5V bias (6 V amplitude adjustable to 3 V), low
output jitter (10 ps typical), and low input drive sensitivity
(250 mV at Vo=6 V).
Primary Applications
• Mach-Zehnder Modulator Driver for
Metro and Long Haul.
Measured Performance
TGA4953 Evaluation Board (Metro MSA Conditions)
10.7 Gb/s, Vplus=5 V, Id=210 mA, (Pdc=1.1 Watt)
Vout=6 Vpp, CPC=50%, Vin = 500 mVpp
Scale: 2 V/div, 15 ps/div
The 4953 requires external DC blocks, a low frequency
choke, and control circuitry.
The TGA4953-EPU is available on an evaluation board.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
