概要
The GN1185 is a quad-channel laser driver designed to be DC-coupled with directly modulated 25Gbps lasers.
Features
- Quad-channel DML laser driver chip, designed for co-packaging with 25Gbps to 28Gbps DFB lasers with impedances of 8Ω to 16Ω
- Power dissipation of GN1185 DML driver = 190mW for four channels (IBIAS = 0mA, IMOD = 0mApp)
- Interfaces with Semtech CDR IC (GN2104)
- Maximum programmable bias current (average current through the laser) = 70mA
- Maximum programmable modulation current = 55mApp (into an 8Ω to 16Ω differential laser load)
- Eye shaping features—crossing point adjust and input equalization
- IBIAS/IMOD monitor output

The Challenge of Drain Grate Maintenance
In urban and industrial water management, drain grates play a crucial role in preventing debris from clogging sewage systems, retention basins and hydropower plants. These grates filter out foliage, branches and other obstructions, ensuring the smooth flow of water. However, over time, debris accumulation can lead to blockages, increasing the risk of flooding and requiring frequent manual inspections.
