HXT42400中文资料28G – 4 Channel DML Driver 10Km数据手册Renesas规格书

描述 Description

The HXT42400 is a low power, Direct Modulated Laser (DML) driver array for CLR4 / LR4 optical applications that supports data rates up to 28Gbps and optical reach up to 10km. In conjunction with a DFB laser diode array or individual DFB laser diodes, the device handles the complete digital-to-optical conversion, including a CML input stage with equalization, laser driver IBIAS and IMOD current drive control, and supervision. Designed for direct DC-coupled anode drive of the DFB laser diode for cost-effective and compact assemblies. Available in die form.
