The GX62474B is a high-performance parallel low Vpi limiting Mach-Zender Modulator (MZM) driver designed for 100G DP-QPSK long-haul optical transmitters. The GX62474B is a small form factor (SFF) with differential inputs and single ended outputs. The GX62474B is a surface mount device (SMD) packaged solution consisting of 4 x 32Gb/s broadband amplifiers, each capable of driving a limiting output voltage of 7.0Vpp suitable for multilevel modulation applications.

Key Features
