GENERAL DESCRIPTION
The S3170 is a high-speed transimpedance amplifier (TIA) for 2.5 Gbps applications. Input currents as high as 2.2 mA can be amplified with low duty cycle distortion. The low input noise allows signals down to 3.7 A (peak to peak) to be detected with a signal to noise ratio of 22 dB (allows for BER< 1E-10). The outputs are voltage limited to 1000 mV, differential, in order to allow a wide input dynamic range without exceeding the input voltage range of the post ( l i m i t i n g ) a m p l i f i e r.
