11.1 Gbps 3.3V  
Transimpedance Amplifier  
Preliminary Technical Data  
ADN2821  
FEATURES  
PRODUCT DESCRIPTION  
Bandwidth: 8 GHz min  
Input Noise Current Density: 12pA√Hz  
Optical sensitivity: −19 dBm1  
The ADN2821_2/5/10 are a series of compact, high  
performance SiGe 3.3V power supply Trans-impedance  
Amplifiers (TIAs) optimized for small form factor 10Gbps  
Metro-Access and Ethernet PD-TIA modules. The ADN2821  
series features low input referred noise current and a range of  
trans-impedance gains, suitable for driving a typical CDR or  
transceiver directly. 8GHz minimum BW enables up to  
11.1Gbps operation; 1.1µA input referred noise current enables  
−19dBm sensitivity; 3.25dBm input overload current at a 10dB  
extinction ratio. RSSI output signal proportional to average  
input current is available for monitoring and alarm generation.  
For assembly in small form factor packages, the ADN2821  
series integrates a photodiode filter RFCF network on chip and  
features 25kHz low frequency cutoff with small 0.5nF external  
capacitor The ADN2821 operates with a 3.3V 0.3V power  
supply and is available in die form.  
Differential Transimpedance /Linear Range:  
ADN2821_2: 2.0 kΩ/0.20 mA p-p  
ADN2821_5: 5.0 kΩ/0.08 mA p -p  
ADN2821_10: 10.0 kΩ/0.04 mA p-p  
Power Dissipation: 150 mW  
Differential Output Swing: 400 mV p-p min  
Input Overload: 3.25 dBm @ 10 dB ER  
Low-F cutoff:  
ADN2821_10: 25 kHz w/CLF = 0.5 nF  
On-Chip PD filter: RF = 200 Ω, CF = 20 pF  
RSSI voltage and current ratio: 0.8V/mA  
Die Size: 0.65 mm × 1.20 mm  
APPLICATIONS  
10.7 Gbps Optical Modules  
SONET/SDH OC-192/STM-64 and 10 GbE  
Receivers, Transceivers, Transponders  
1 10-12 BER, 10 dB extinction ratio, 0.85 A/W PD responsivity.
