NeoPhotonics Ships Over One Million Drivers

News

53 Gbaud GaAs PAM4 driver chips target 100G and 400G hyperscale data centre networks

NeoPhotonics has announced that it has shipped more than one million single and quad drivers for PAM4 transceivers used in hyperscale data centre networks. NeoPhotonics 53 Gbaud PAM4 driver IC is a linear, differential driver based on GaAs and optimised for 1 x 100 Gbps, 4 x 100 Gbps and 8 x 100 Gbps PAM4-based applications. The drivers are in volume production and provide a high RF output voltage swing with high linearity and are well-suited to modulate silicon photonics Mach-Zender Modulators (MZM) used in 400G data centre transceivers, while maintaining exceptional Quaternary Transmitter Dispersion Eye Closure (TDECQ).

“We are pleased to have achieved multiple design wins for our family of 53 Gbaud suite of drivers and are now shipping them in high volume. We have been shipping GaAs drivers for nearly a decade and have a deep technology base. We started with 10 Gbps devices, and are now shipping devices for 400 Gbps transceivers,” said Tim Jenks, chairman and CEO of NeoPhotonics. “We continue to improve our product performance and have recently introduced versions of the driver that deliver more than 20 percent power reduction. Furthermore, we are currently developing next-gen versions that we believe will feature 50 percent power savings verses the current generation,” concluded Jenks.
