S8046 is optical communication devices designed for POF (Plastic Optical Fiber) data links. S8046 is a high sensitivity, high-speed
photo IC that receives signals at 50 Mbps and covers a wide dynamic range of 21.5 dB. The output is TTL compatible. S8046 also
features a sleeping mode in which operation automatically switches to low power dissipation mode when no light is input and
switches back to normal operation mode when light is input from the optical fiber. The internal IC checks which mode is currently
selected and this check signal is available from the mode output terminal. Current consumption in sleeping mode is approximately
1/400th that of normal operation mode.
