3.3 V, 3.2 Gbps,  
Limiting Amplifier  
ADN2891  
FEATURES  
GENERAL DESCRIPTION  
Input sensitivity: 4 mV p-p  
80 ps rise/fall times  
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.  
CML outputs: 700 mV p-p differential  
Programmable LOS detector: 3.5 mV to 35 mV  
Rx signal strength indicator (RSSI)  
SFF-8472-compliant average power measurement  
Single-supply operation: 3.3 V  
Low power dissipation: 145 mW  
Available in space-saving 3 mm × 3 mm, 16-lead LFCSP  
Extended temperature range: −40°C to +95°C  
SFP reference design available  
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.  
APPLICATIONS  
SFP/SFF/GBIC optical transceivers  
OC-3/OC-12/OC-48, GbE, Fibre Channel (FC) receivers  
10GBASE-LX4 transceivers  
Additional features include a programmable loss-of-signal  
(LOS) detector and output squelch.  
WDM transponders  
The ADN2891 is available in a 3 mm × 3 mm, 16-lead LFCSP.
