The ONET2804T is suitable for parallel optical interconnects in applications with data rates of up to 28Gbps, such as optical line cards, point-to-point microwave backhauls and video over fibre. The TIA’s 750μm channel pitch reduces system complexity by allowing designers to wire bond directly to a photodiode. A two-wire I2C interface allows designers to optimise systems in order to drive high performance at low power consumption.
Operating over a temperature range from -40 to +100°C, the ONET2804T features 21GHz bandwidth, a gain of 10kΩ, a received signal strength indicator for each channel and a differential output amplitude of 450mVPP.
The TIA operates from a single 3.3 V supply and is available in die form.
