PHY1092
Transimpedance Amplifier
The PHY1092 is a transimpedance amplifier designed for use within small form factor fibre optic modules targeted at Gigabit Ethernet and SONET/SDH applications. Working from a 3.3V power supply the PHY1092 integrates a low noise transimpedance amplifier, with a typical transimpedance of 8.5kW, an AGC and an output stage. A signal is also provided which can be used to implement a signal strength monitor circuit. Typical sensitivity of -27.5dBm can be achieved at 1.25Gbps at a wavelength of 1310nm. The PHY1092 is available in die form for mounting on a header to create a ROSA when combined with suitable optics and Photo-detector diode.
