10.7 Gbps Low Noise, High Gain Transimpedance Amplifier IC with Performance Monitor
The ADN2820 is a compact, high performance SiGe transimpedance amplifier (TIA) optimized for 10 Gbps metro access and Ethernet applications. It is a single-chip solution for detecting photodiode current with a high gain differential output voltage for use in any optical module. With exceptionally low input noise and a high transimpedance, the ADN2820 can directly drive a CDR or transceiver without need of an external post amplifier. Not only is overall performance augmented by the elimination of noise contribution from the post amplifier, but design complexity is simplified and manufacturability improved with reduced space and power consumption. The feature set of the ADN2820 includes functionality previously found in post amplifiers, providing the same level of flexibility as more complex solutions. Slice (offset) adjust is included to minimize duty cycle distortion, while an analog power monitor is incorporated to enable loss of power alarms.
The ADN2820 operates from a single power supply at +3.3V. It is available in die form.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
