General Description

The ADN2890 is a high gain, limiting amplifier optimized for use in SONET, Gigabit Ethernet (GbE), and Fibre Channel optical receivers that accept input levels of up to 2.0 V p-p differential and have 3 mV p-p differential input sensitivity.

The ADN2890 provides the receiver functions of quantization and loss of signal (LOS) detection.

The ADN2890 can easily operate at up to 3.2 Gb/s to support LX4 transceivers.
