ADN2890 Limiting Amplifier

ADN2890 Limiting Amplifier

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 quantizatio.
