The SL82018 is a multi-rate, high
performance transimpedance amplifier (TIA) with integrated limiting
amplifier (LA). The device was optimized for power critical optical data
transport applications with respect to various transmission standards.
The SL82018 features a low input referred noise, which enables a
BER of 10-12 at 6 Gbps for an input current of 20 μApp.
This allows for an optical input sensitivity of better than -15 dBm
if connected to a typical photodiode.
As an additional feature the SL82018 integrates a sophisticated wake-up
circuit, which sets the receiver into “Sleep Mode” operation with less
1 μA supply current when no optical input signal is detected.
To facilitate assembly in small form factor packages the SL82018
integrates the photodiode filter network on chip.
The SL82018 chip area is approximately 0.5 mm˛. The device operates from
a dual 1.5 V and 2.5 V power supply, a dual 1.5 V and 3.3 V power supply
or a single 3.3 V power supply and is available in bare die form with an
option for solder ball bumps.
