The ADN2891 is a 3.2 Gbps limiting amplifier with integrated loss-of-signal (LOS) detection circuitry and a received signal strength indicator (RSSI). This part is optimized for SONET, Gigabit Ethernet (GbE), and Fibre Channel optoelectronic conversion applications. The ADN2891 has a differential input sensitivity of 4 mV p-p and accepts up to a 2.0 V p-p differential input overload voltage. The ADN2891 supports current mode logic (CML) outputs with controlled rise and fall times. By monitoring the bias current through a photodiode, the onchip RSSI detector measures the average power received with 2% typical linearity over the entire valid input range of the photodiode. The on-chip RSSI detector facilitates SFF-8472compliant optical transceivers by eliminating the need for external RSSI detector circuitry.
