Product Description
The TriQuint TGA4956-SM is a MZ and low
voltage modulator driver amplifier designed to
operate at frequencies that target the 10 Gb/s
optical market using an economical 8x8 mm
surface mount package.
11.32 Gbps, PRBS 231 -1, Vin = 1Vpp, Vout = 3.0 Vpp, Rise / Fall time
= 22.2 / 23.1 ps, Additive RMS Jitter = 1.9 ps, Extinction Ratio = 13.7 dB

The TGA4956-SM consists of two high
performance wideband amplifiers combined with
off chip circuitry assembled in a surface mount
package. A single TGA4956-SM placed between
the MUX and Optical Modulator provides OEMs
with a low-cost, surface mount modulator driver
solution.
The TGA4956-SM provides Metro and Long Haul
designers with scalable power dissipation for
varying output drive requirements (< 0.42 W at Vo
= 3 Vpp, <1 W at Vo = 6 Vpp).
ROHS compliant, Moisture Sensitivity Level 1.
Evaluation boards available upon request.
