ONET8501VRGPT

Overview

The ONET8501VRGPT is a high-speed laser driver designed for direct modulation of Vertical-Cavity Surface-Emitting Lasers (VCSELs). It supports data rates up to 11.3 Gbps and operates on a single 3.3V supply with a voltage range of 2.95V to 3.6V. The device features a two-wire digital interface for configuration, including digitally selectable input bandwidth and adjustable loss-of-signal thresholds. Packaged in a 20-pin QFN (4x4 mm) format, it draws approximately 90 mA of operating current and functions within a temperature range of -40°C to +85°C.
