概览

The GN2010D is an integrated bi-directional CDR, DFB/FP laser driver and limiting amplifier for XFP & SFP+ SONET, 10GBase-LR Ethernet and 8.5Gb/s Fibre Channel applications.

它是一种高度集成、低功耗、小尺寸的器件，是小型光学模块的理想选择。

传输路径由可选的输入均衡、多速率 Tx CDR 和 DFB 激光驱动器组成。接收路径由具有可编程均衡的限幅放大器、多速率 Rx CDR 和输出去加重组成。发射和接收方向都提供高度可配置的眼图成型功能，可实现最佳的电和光输出。两个方向还提供极性反转、环回、输出静音和可编程输出均衡选项。

The GN2010D has an integrated analog to digital converter, which through the serial interface, provides digital diagnostic information on supply voltage, die temperature, laser bias current, and transmit optical power. The GN2010D is configurable for multi-rate operation. The GN2010D also offers integrated laser safety features.

The GN2010D device is packaged in a small-outline 5mm × 5mm 32-pin, high-frequency QFN package with exposed pad. The GN2010D is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous sub-components are RoHS compliant.
