General Description
Pin Configuration
The TriQuint TGA4947-MOD is a 4-channel optical
modulator driver amplifier designed to operate at
frequencies that target the 100 Gb/s optical market
using a 45.0 x 33.4 x 7.0 mm surface mount
module.
The TGA4947-MOD consists of four channels of
high performance wideband amplifiers and
integrated broadband bias tees, DC blocking caps,
and necessary bypass caps assembled in a metal
surface mount housing. A single TGA4947-MOD
placed between the MUX and OIF compliant
Optical Modulator provides OEMs with a modulator
driver solution.
The TGA4947-MOD provides Metro and Long Haul
designers with system critical features such as: low
power dissipation, high signal to noise (SNR) ratio,
high voltage drive capability (3 Vpp amplitude
adjustable up to 9 Vpp), low output jitter, and low
input drive sensitivity (0.4 Vpp 1 Vpp at Vout = 8
Vpp).
The TGA4947-MOD finish is lead-free. RoHS
compliant. Evaluation boards and bias boards are
available upon request.
