It features low input referred noise, 8 GHz bandwidth, 5.5 kΩ small signal transimpedance, automatic gain control (AGC) which provides highly linear operation and a received signal strength indicator (RSSI). The ONET8511T is available in die form, includes an on-chip VCC bypass capacitor and is optimized for packaging in a TO can and for the use together with electronic dispersion compensation (EDC) ICs. The ONET8511T requires a single +3.3 V supply and its power efficient design typically dissipates less than 160 mW. The device is characterized for operation from -25°C to 100°C (IC back side) temperature.. 1 Please b...
