米硅科技发布新一代400Gbps四通道线性跨阻放大器，将亮相APE 2024

  ICC讯 近日，上海米硅科技有限公司(简称：米硅科技）宣布，其新一代400Gbps四通道线性跨阻放大器ms82040正式开始提供样片及技术支持，该芯片适用于IEEE P802.3bs 400GBASE-LR4 光模块等应用。

  Lately， Shanghai Minisilicon Technology Co., Ltd(Minisilicon) announced that its new 400Gbps PAM4 four-channel linear transimpedance amplifier, the ms82040,  has officially begun providing samples and technical support. The TIA is suitable for IEEE P802.3bs 400GBASE-LR4 optical transceiver and other applications.

  米硅科技研发总监Wendy说：“ms82040非常适合COB 和硅光领域中的各种PAM4光学器件。米硅科技期望通过行业领先TIA/CDR/Driver 技术，加速部署下一代单通道100G光收发器方面继续发挥技术优势，迎接TB光网络时代。”

  Wendy, R&D Director of Minisilicon, stated "ms82040 is ideal for various PAM4 optics for COB and SiPHO. Minisilicon aims to extend its advantages in  TIA/CDR/Driver technology to help accelerate the deployment of next-generation single-channel 100G optical transceivers to embrace the era of Terabyte optical networks. "

  随着以ChatGPT为代表的大数据和人工智能AI应用快速发展，海内外数据中心网络用光模块的速率正快速向400G/800G演进，需要光模块支持更高的单波速率以及多通道应用。伴随整个数据中心的规模化普及，国内外市场对400Gbpcs以上速率光模块的需求日益增多。

  With rapid development of big data and AI applications like ChatGPT, the speed of optical modules for data center networks is rapidly evolving to 400G/800G. This rapid evolution requires optical modules to support higher single-wave rates and multi-channel applications. With the popularization of the scale of the entire data center, the domestic and foreign markets are increasingly demanding 400Gbpcs and above rate optical modules.

  米硅科技ms82040是一款四通道56GBaud线性跨阻/可调增益放大器。适用于4*100Gb/s PAM4光模块应用。芯片支持MGC（手动增益控制）或AGC（自动增益控制）两种模式和非常宽的输入光功率和极低的输入参考噪声电流密度。它在3.7KΩ阻抗（典型值）时具有 11pA/√Hz的极低的输入噪声电流密度，在56G波特率下放大功率高达2.1mApp，实现信号传输的快速响应、低延时和高增益。

  The ms82040 is a quad 56GBaud linear transimpedance/adjustable gain amplifier suitable for 4*100Gb/s PAM4 optical module applications. This chip supports either MGC (Manual Gain Control) or AGC (Automatic Gain Control) modes. It provides a broad range of optical  power and extremely low input reference noise current density. It features a very low input noise current density of 11pA/√Hz at 3.7KΩ impedance (typical) and amplified power up to 2.1mApp at 56G baud rate, enabling fast response for signal transmission, low latency, and high gain.

  同时，ms82040内部集成了I2C 接口，可实现实时控制和状态读取。此外，芯片提供RSSI功能，用于监控和报告低至暗电流的平均光输入功率水平。在过载条件下，VPD 提供可高于VCC的偏置电压，从而实现最佳光电二极管性能。

  At the same time, I2C for real-time control and status reading has been integrated in ms82040. In addition, the chip provides RSSI function for monitoring and reporting average optical input power levels down to dark current. Under overload conditions, VPD provides a bias voltage that can be higher than VCC for optimal photodiode performance.

  ms82040采用直接打线到PAD的设计，通道间距为750um但是芯片尺寸只有3.174mm*1.074mm。功耗等各项参数处于国内前沿水平，同时具有极优的性价比，目前已与市场上主流商用PD联合测试，性能良好，OMA在BER≤2.4E-4条件下三温均达到-9.4dbm以上，欢迎各位新老客户到访米硅展位DB-12交流探讨。

  ms82040 adopts the design of direct wire bonding to PAD with pitch 750um, chip size is 3.174mm*1.074mm. Power consumption and other parameters are leading level of domestic competitors. It is best choose for both excellent performance and cost reduction. ms82040 has been tested with the mainstream commercial PDs with very good performance, OMA in the BER ≤2.4E-4 conditions of the three temperatures are more than -9.4dbm.
