Photo IC for optical link
L12557-01SR, S12423-01SR
Transmitter/receiver photo IC for DC to 10
Mbps optical link
The L12557-01SR transmitter photo IC combines a 650 nm red LED, which is suitable for plastic optical fiber (POF) communication, and a driver IC. It has a mini molded lens suitable for coupling to the POF. It supports communication speeds ranging
from DC to 10 Mbps. The S12423-01SR receiver photo IC has monolithically integrated PIN photodiode and signal processing
circuit. It features small size and strong resistance to electromagnetic induction noise. The S12423-01SR generates digital
output (CMOS).

*1: Power dissipation decreases at a rate of 1.75 mW/°C above Ta=25 °C.
*2: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
