米硅科技發(fā)布新一代400Gbps四通道線性跨阻放大器，將亮相APE 2024

  ICC訊 近日，上海米硅科技有限公司(簡稱：米硅科技）宣布，其新一代400Gbps四通道線性跨阻放大器ms82040正式開始提供樣片及技術支持，該芯片適用于IEEE P802.3bs 400GBASE-LR4 光模塊等應用。

  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.

  米硅科技研發(fā)總監(jiān)Wendy說：“ms82040非常適合COB 和硅光領域中的各種PAM4光學器件。米硅科技期望通過行業(yè)領先TIA/CDR/Driver 技術，加速部署下一代單通道100G光收發(fā)器方面繼續(xù)發(fā)揮技術優(yōu)勢，迎接TB光網絡時代?！?

  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. "

  隨著以ChatGPT為代表的大數據和人工智能AI應用快速發(fā)展，海內外數據中心網絡用光模塊的速率正快速向400G/800G演進，需要光模塊支持更高的單波速率以及多通道應用。伴隨整個數據中心的規(guī)?；占?，國內外市場對400Gbpcs以上速率光模塊的需求日益增多。

  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線性跨阻/可調增益放大器。適用于4*100Gb/s PAM4光模塊應用。芯片支持MGC（手動增益控制）或AGC（自動增益控制）兩種模式和非常寬的輸入光功率和極低的輸入參考噪聲電流密度。它在3.7KΩ阻抗（典型值）時具有 11pA/√Hz的極低的輸入噪聲電流密度，在56G波特率下放大功率高達2.1mApp，實現信號傳輸的快速響應、低延時和高增益。

  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.

  同時，ms82040內部集成了I2C 接口，可實現實時控制和狀態(tài)讀取。此外，芯片提供RSSI功能，用于監(jiān)控和報告低至暗電流的平均光輸入功率水平。在過載條件下，VPD 提供可高于VCC的偏置電壓，從而實現最佳光電二極管性能。

  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采用直接打線到PAD的設計，通道間距為750um但是芯片尺寸只有3.174mm*1.074mm。功耗等各項參數處于國內前沿水平，同時具有極優(yōu)的性價比，目前已與市場上主流商用PD聯合測試，性能良好，OMA在BER≤2.4E-4條件下三溫均達到-9.4dbm以上，歡迎各位新老客戶到訪米硅展位DB-12交流探討。

  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. Welcome friends and customers visit Minisilicon Booth#DB-12 explore the future opportunities.
