LED/PHOTO IC Transmitter/receiver photo IC for optical link L8628, S8627-01A For MOST automotive network, 50 Mbps band POF communications L8628 and S8627-01A are transmitter and receiver photo ICs developed for MOST (Media Oriented System Transport) networks used in vehicles to communicate multimedia information. The transmitter photo IC L8628 consists of a red LED, driver IC and current regulator chip incorporated into a clear plastic package and can be set to an operating mode that reduces the optical output level by half. The receiver photo IC S8627-01A is a monolithic photo IC fabricated by the PiN-BiP process and features a wide dynamic range. It also has a low power consumption "sleeping mode" and an optical wakeup mode triggered by input of light. Both the transmitter and receiver photo IC input and output digital signals through a TTL interface.
