40Gbps LiNbO3 Modulator Driver, Centellax OA4SMM5, Single Input RF Amplifier
The OA4SMM5 is a small high performance broadband 40Gb/s Electro-Absorption and Lithium Niobate optical modulator driver amplifier with low jitter, 3.3V amplitude, and excellent gain and group delay flatness to 45GHz. The driver is designed for electro-optical test equipment and SONET OC-768 / STM-256 optical modulator driver applications.

Product Highlights
• 3.3Vp-p output swing
• 0.5ps added RMS jitter
• 6ps rise / fall time
• 20dB gain to 45GHz
• 900mW power dissipation
• Size: 0.77 x 1.19 x 0.26 inch
• Standard GPPO RF connectors
Application
The OA4SMM5 is offered in a small modularized package with excellent performance, and is intended for transponder integration. The OA4SMM5 has gain and power levels that are ideally suited for driving 40G electro-absorption modulators. The driver has low power dissipation, ample drive signal, low added jitter, fast rise/fall times, and is easy to use with simple bias voltages. The OA4SMM5 can be biased from a standard 5V supply.
