技术问答

目前高速光模块解决方案主流应用有两种，一种是DSP方案，另外一种是模拟CDR方案。对于光模块发射和接收端的器件选择是整个光模块方案的关键。DSP方案中，在DSP芯片中集成了driver和CDR功能，处理信号高效而稳定，信号质量好，但是DSP方案在性能优良的同时，也面临着高功耗，高成本的问题。CDR方案与DSP方案相比，在性能好，功耗低的同时，还具备低成本的巨大优势。下面主要介绍瑞萨HXR14450芯片所特有的优势以及应用。

瑞萨HXR14450是专门为高速光模块解决方案而设计的光膜开接收端TIA，该芯片的主要特点为，多通道，集成度高，低成本，低功耗，高性能，目前在200/400/800G QSFP-DD SR PAM4高速光模块数据中心互联等领域广泛应用。

多通道：该芯片是一个四通道，每端口速率高达56 G bps PAM4调制速率，200G模块单机用量仅需一颗。

低成本：芯片采集用传统成熟的28nm CMOS工艺，成本大概是DSP方案芯片的一半。

低功耗：每颗芯片功耗约为3.5w，相比同类芯片每通道功耗低约50w。

高性能：瑞萨HXR14450是一个四通道，每个通道集成时钟和数据恢复(CDR)单元，CDR内部包含DFAE，处理信号的能力强。

由于集以上优势于一身，可作为PAM4的下一代数据通信的调制芯片。主要应用在200G QSFP56 SR4 & 400G QSFP-DD或OSFPSR8以太网模块，400G SR OBO和AOC等。，尤其在大型互联和数据中心200G/400G高速光模块项目中应用广泛。

【应用】输出电流500mA，尺寸仅1x1mm的国产LDO RS3236用于400G QSFP-DD光模块

400G QSFP-DD光模块中，会用到4路TIA，它需要配备供电电压为1.8V的LDO。因TIA要求及光模块自身特点，要求该LDO应具备大电流、噪声低、小体积、低成本等特点。润石科技推出的LDO RS3236，具备输出电流大、噪声低、小体积、低成本等特性，可完全胜任400G QSFP-DD对LDO的需求。
