PHY1096

High Sensitivity Transimpedance Amplifier

The PHY1096-01 is a transimpedance amplifier designed for use within small form factor fibre optic modules targeted at Gigabit capable Passive Optical Network (GPON) applications.

Working from a 3.3V power supply the PHY1096-01 integrates a low noise transimpedance amplifier, with a typical differential transimpedance of 34kW, an AGC amplifier and an output stage.

An output is also provided which can be used to implement a signal strength monitor circuit. This is designed to sink or source a current equal to the photodiode current for ease of interfacing.

The PHY1096-01 is available in die form for mounting with suitable optics and photodiode.
