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 on-chip 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 ADN2891 is available in a 3 mm × 3 mm, 16-lead LFCSP.

Applications

  • SFP/SFF/GBIC optical transceivers
  • OC-3/OC-12/OC-48, GbE, Fibre Channel (FC) receivers
  • 10GBASE-LX4 transceivers
  • WDM transponders
