SY88782L

SY88782L 3.3V, 1.25Gbps High-Current, Low-Power Laser Driver for Datacom Telecom Applications General Description The SY88782L is a single supply 3.3V low power consumption, small-form factor, driver for telecom/datacom applications using FP/DFB lasers at data rates up to 1.25Gbps. The driver can deliver modulation current up to 90mA, and the high compliance voltage it offers makes the part suitable for high-current operation (with the laser AC- or DCcoupled to it.) This device is intended to be used with Micrel MIC3003 Optical Transceiver Management IC which allows for modulation and bias currents control and monitoring, automatic power Control, and temperature compensation. All support documentation can be found on Micrel’s web site at: www.micrel.com.
