GN2105B-IBE3

Overview

The GN2105B-IBE3 is a low-power quad ClearEdge® Clock and Data Recovery (CDR) device with an integrated Distributed Mode Laser (DML) driver, designed for 24 Gbps to 28 Gbps signal conditioning. It features reference-free operation and proprietary DML compensation technology to maximize performance across multiple laser vendors. The component enables sub-3.5W power consumption in 100G QSFP28 PSM4, CWDM4, and LR4 module designs when paired with compatible TIAs such as the GN2104S or GN2110B. Its DC-coupled DML driver supports flexible Chip-on-board and passive TOSA configurations.
