Product Details
The ADN2892 is a 4.25 Gbps limiting amplifier with integrated loss of signal (LOS) detection circuitry 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 1× FC and GbE.
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-8472-compliant optical transceivers by eliminating the need for external RSSI detector circuitry.
Additional features include a programmable loss-of-signal (LOS) detector and output squelch. The ADN2892 is available in a 3 mm × 3 mm, 16-lead LFCSP.
