The ADN2892 is a 4.25 Gbps limiting amplifier with integrated loss of signal (LOS) detection circuitr y and a received signal strength indicator (RSSI). This part is optimized for Fibre Channel (FC) and Gigabit Ethernet (GbE) optoelectronic conversion applications. The ADN2892 has a differential input sensitivity of 3.5 mV p-p and accepts up to a 2.0 V p-p differential input overload voltage. The ADN2892 has current mode logic (CML) outputs with controlled rise and fall times. The ADN2892 has a selectable low-pass filter with a -3 dB cutoff frequency of 1.5 GHz. By setting BW_SEL to Logic 0, the filter can limit the relaxation oscillation of a low cost CD laser used in a legacy 1 Gbps FC transmitter. The limited BW also reduces the rms noise and in turn improves the receiver optical sensitivity for a lower data rate application, such as 1x FC and GbE.
