Overview

The GX72170 is a high-performance linear Mach-Zender Modulator (MZM) driver designed for 100G DP-QPSK and 200G/400G DP-mQAM metro, and long-haul optical Small-Form-Factor (SFF) transmitters.

The GX72170 is a broad band and ultralow power SiGe single-channel amplifier die, and integrates a linear pre-amplifier and a post-amplifier with AC-coupled differential input and differential output interfaces. The device can drive a linear output voltage of 3.0Vppd with differential characteristic impedance of around 50Ω.
