概要
The Gennum® GN1058 is a fully integrated silicon germanium (SiGe) BiCMOS transimpedance amplifier, providing wideband low noise pre-amplification of a current signal from a PIN photodiode or APD.
The GN1058 is intended for use in SFP+ applications. It features differential outputs and incorporates automatic gain control (AGC) to improve linear dynamic range. A decoupling capacitor on the supply is the only external component required.
Features
- Single +3.3V power supply
- Power dissipation 190mW (typical)
- Bandwidth remains constant over dynamic range
- Typical small signal gain of 4kΩ
- RSSI (Receive Signal Strength Indicator)
- Operates from 9.95Gbps to 11.3Gbps NRZ
アプリケーション
- ITU/IEEE-based transmission systems, test equipment and modules, especially intended for 10GBASE-LRM SFP+ applications
- OC-192 fibre optic modules and line termination
- 10 Gigabit Ethernet
- Fibre Channel
- Serial data systems up to 11.3Gbps

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.
