The GX62474 is a high-performance parallel low Vpi linear Mach-Zender Modulator (MZM) driver designed for 100G DP-QPSK long-haul optical transmitters. The GX62474 is a Small Form Factor (SFF) with differential inputs and single ended outputs. The GX62474 is a surface mount device (SMD) packaged solution consisting of 4 x 32 GB/s broadband amplifiers, each capable of driving a linear output voltage of 6.5Vpp suitable for multilevel modulation applications.
