Red LED/Photo IC for optical link

L8045/S8046

L8045 and S8046 are optical communication devices designed for POF (Plastic Optical Fiber) data links. L8045 is a highly

reliable, high-power LED that emits red light with a peak at 650 nm optimized for POF. A mini-lens is molded on the package for

efficient coupling to a POF. When used with our recommended driver circuit, a 50 Mbps transmitter can be configured at low cost.

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.
