VI Systems launches 56G NRZ VCSEL driver and TIA chips

VI Systems offers the first generation of 56 Gbit/s laser driver and amplifier chips which are designed for Non-Return-to-Zero (NRZ) modulation in latency critical optical communication links.

VI Systems GmbH launches a set of VCSEL (vertical surface emitting laser) driver and limiting transimpedance amplifier (TIA) chip for 56 Gbit/s Non-Return-to-Zero (NRZ) modulation. The new generation of ICs are designed for differential signal input or output channels. The chips feature a low power consumption of less than 280 mW with a small die size of 0.64 x 1.04 mm.  The operation voltage is specified up to 3.3V.

The graphs shows the bandwidth simulation versus the actual measurement of the VCSEL driver IC at characteristic bias conditions. The -3dB modulation bandwidth is up to ~63 GHz.

The specification 56 Gbit/s NRZ for very short and ultra-short reach interconnects have recently be completed within the CEI-56G standard by the Optical Internet Working Forum (OIF).

Customer samples of the VCSEL driver and TIA chip are available now.

The development was funded by the European Union’s Horizon 2020 research and innovation programme under grant agreement No 666866.
