Microchip Technology, Inc. Laser Drivers SY88952LMI

The SY88952LMI is a programmable laser driver designed for SONET/SDH applications, capable of operating at data rates up to 2.7Gbps. It operates with a single 3.3V power supply and features rise and fall times of less than 75ps. The device supports independent programmable bias and modulation currents, with a bias current capability of up to 100mA and modulation current up to 90mA. An automatic average power control (APC) feature is integrated to maintain consistent optical output power across varying temperatures and device lifetimes. The SY88952LMI includes bias and modulation current monitors, as well as safety features that trigger alarms under specific conditions, ensuring reliable operation. The device is available in a 32-pin EPAD-MLF,Ñ¢ package and is suitable for applications such as OC-48 transceivers, SONET/SDH transmission systems, and metro area networks. It operates within an ambient temperature range of -40¬8C to +85¬8C and complies with ANSI, ITU, and Bellcore SDH/SONET specifications.
