PRODUCT DESCRIPTION
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.
1 10-12 BER, 10 dB extinction ratio, 0.85 A/W PD responsivity.
