3.3 V 4.25 Gb/s  
Limiting Amplifier  
Preliminary Technical Data  
ADN2892  
The ADN2892 is a high gain, limiting amplifier optimized for  
use in Fibre Channel and GbE optical receivers. The ADN2892  
accepts input levels of up to 2.0 V p-p differential and has 3 mV  
p-p differential input sensitivity. The ADN2892 provides the  
receiver functions of quantization and loss of signal (LOS)  
detection.  
FEATURES  
SFP reference design available  
Input sensitivity: 3 mV p-p  
65 ps rise/fall times  
BW Select to support Multi-Rate 1x/2x/4x FC modules  
Optional LOS Output Inversion to support SFF  
CML outputs: 700 mV p-p differential  
Programmable LOS detector: 3 mV to 45 mV  
Rx signal strength indicator (RSSI):  
SFF-8472 compliant average power measurement  
The ADN2892 has an on-chip selectable filter to reduce the BW  
of the limamp to 1.5GHz in order to filter out the relaxation  
oscillation of legacy 1Gb/s Fiber Channel transmitters with CD  
lasers. The reduced BW will also allow for more optical Rx  
sensitivity margin at the lower data rates such as 1xFC and  
1GbE in multi-rate modules.  
Single supply operation: 3.3 V  
Low power dissipation: 160 mW  
Available in space-saving 3 × 3 mm 16-lead LFCSP  
Increased Temperature Range: -40oC to 95oC  
The limiting amplifier also measures average received power  
based on a direct measurement of the photodiode current with  
better than 1 dB of accuracy over the entire input range of the  
receiver. This eliminates the need for external average Rx power  
detection circuitry in SFF-8472 compliant optical transceivers.  
APPLICATIONS  
SFP/SFF/GBIC optical transceivers  
1x/2x/4x Multi-rate Fibre Channel receivers  
LX4  
The ADN2892 limiting amplifier operates from a single 3.3 V  
supply, has low power dissipation, and is available in a space-  
saving 3 × 3 mm 16-lead lead frame chip scale package  
(LFCSP).
