VI Systems offers 56-Gbps NRZ laser driver and transimpedance amplifier for CEI-56G applications

VI Systems GmbH says its sampling a vertical cavity surface emitting laser (VCSEL) driver and limiting transimpedance amplifier (TIA) for 56-Gbps non-return-to-zero (NRZ) modulation. The chips are designed for latency critical optical communication links, such as very short and ultra-short reach interconnects based on the CEI-56G standard by the Optical Internetworking Forum (OIF).

This set of ICs are intended for differential signal input or output channels. The chips feature a power consumption of less than 280 mW, with a die size of 0.64x1.04 mm, and operation voltage specified up to 3.3 V.
