10/11.3 Gb/s Transimpedance Amplifier with Automatic Gain Control for SFP+ Applications
Gennum's 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.
