SY88782L 3.3V, 1.25Gbps High-Current, Low-Power Laser Driver for Datacom Telecom Applications General Description Features The SY88782L is a single supply 3.3V low power 2.3V minimum laser compliance voltage consumption, small-form factor, driver for 48mA power supply current typical telecom/datacom applications using FP/DFB lasers Operation up to 1.25Gbps at data rates up to 1.25Gbps. The driver can deliver Modulation current up to 90mA modulation current up to 90mA, and the high compliance voltage it offers makes the part suitable Designed for use with the MIC3003 for high-current operation (with the laser AC- or DC- Small form factor 3mm x 3mm QFN package coupled to it.) This device is intended to be used with Micrel MIC3003 Optical Transceiver Applications Management IC which allows for modulation and Multi-rate LAN, MAN applications up to 1.25Gbps: bias currents control and monitoring, automatic Ethernet, SONET OC3/12/24 and SDH power Control, and temperature compensation.
