The SL82015 is a multi-rate, high performance
transimpedance amplifier (TIA) with integrated limiting amplifier (LA)
for silicon photodiodes.
Together with its VCSEL-driver counterpart (SL82020), the SL82015 was
optimized for power critical optical data transport applications with
respect to various transmission standards.
The SL82015 features a low input referred noise, which enables a BER of
10-12 at 1.5 Gb/s for an input current of 10 µApp.
This allows for an optical input sensitivity of about -16 dBm if
connected to a typical photodiode.
As additional feature the SL82015 integrates a sophisticated wake-up
circuit, which at idle states sets the receiver into “Sleep
Mode”-operation with less than 1 µA supply current.
To facilitate assembly in small form factor packages the SL82015
integrates the photodiode filter network on chip.
The SL82015 chip area is less than 0.5 mm˛, operates from a dual 1.2 V
and 2.5 V power supply and is available in bare die form.
