Photo IC for optical link
This photo IC is capable of data communication at a data rate of 150 Mbps through a plastic optical fiber (POF). Its transmitter is composed of a 650 nm RC (resonant cavity) type LED, which is suitable for POF communications, and a driver circuit that supports an LVDS interface.The transmitter has a built-in temperature compensation function that adjusts for the reduction in the light emission power caused by the high temperature emitted from the RC type LED. This function makes light emission with stable power possible over a wide temperature range. The receiver is composed of a PIN photodiode and signal processing circuit. The adoption of a full differential structure using a dummy photodiode eliminates the effects of external noise, achieving high sensitivity. In addition, the photo IC has a sleep function that suppresses power consumption by switching to standby mode when there is no input.This product features high quality and high reliability, allowing it to be installed even in automobiles for in-vehicle networking. It is already used as an optical fiber transceiver (FOT) for a MOST network, which is a type of in-vehicle multimedia network.
