SY84782U中文资料Laser Diode Drivers数据手册Microchip规格书

描述 Description

The SY84782U is a single 2.5V supply, ultra-low power, small form factor laser diode driver for telecom/datacom applications. Intended to drive FP/DFB lasers at data rates up to 1.25Gbps, it is especially useful for Compact SFP, SFP and SFF modules where power requirements are quite stringent. The driver can deliver modulation current up to 90mA and offers a high compliance voltage, all of which make the SY84782U suitable for high current operations in both AC and DC coupled applications.The SY84782U is intended to be used with Micrel’s MIC3003 Optical Transceiver Management IC, which allows for both modulation and bias current control and monitoring. Furthermore, the MIC3003 offers power control and temperature compensation.This device operates across the industrial temperature range (–40°C to +95°C) and is available in a small 3mm x 3mm QFN package.
