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 distor-
tion. The low input noise allows signals down to 3.7
μ
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, differen-
tial, in order to allow a wide input dynamic range
without exceeding the input voltage range of the post
(limiting) amplifier. Figure 1 shows a typical
application.
