Equipped with a rewriteable register mode! Introduction of temperature compensation technology using OTP memory.
By incorporating OTP memory and sensors into analog circuits, it enables the control of voltage or current based on information from the sensors. Our VCSEL driver IC "PH1025LDBE" features a temperature compensation function that adjusts the bias current and modulation current to maintain a constant VCSEL output power that varies with temperature, by integrating OTP memory and a temperature sensor. In addition to OTP memory, it also includes a writable register mode, allowing for the experimental determination of optimal bias current values and modulation current values for each temperature. 【Features】 ■ Control of voltage or current based on information from sensors ■ Built-in OTP memory and temperature sensor (PH1025LDBE) ■ Includes writable register mode ■ Ability to experimentally determine optimal bias current values and modulation current values for each temperature ■ OTP board equipped with test signal I/F *For more details, please refer to the PDF document or feel free to contact us.
