Xinyun Technology Launches Low-Cost Integrated CDR Chipsets Optimized for Next Generation Datacom and Telecom Networks

     Hangzhou Xinyun Technology Co., Ltd. (hereinafter referred to as Xinyun Tech) has recently completed the development of its next generation CDR product family, successfully launched monolithically integrated CDR and transimpedance amplifier ICs, such as XY5424 for 100G LR4/CWDM4/PSM4 applications and XY5424V for 100G SR4 applications. The XY5424 integrated CDR/TIA product family are single-chip products supporting 4x25/28G dual-rate applications, ideally suited for the ever increasing market requirements of higher bandwidth, higher speed, smaller size and lower cost. The launch of these differentiating products follows the successful mass production and volume shipments of its 100% internally-developed CDR product family.


     Xinyun Tech’s 100G CDR+TIA products (XY5424 product family) are differentiating, high-quality complete product solutions developed and driven by the goal to support 5G and 100G+ high-speed network deployment with domestic IC products. This product family fully supports the construction of Data Center infrastructure in digital transformation, and empowers many major national projects such as the East-to-West Computing Resource Transfer Project. For Xinyun Tech, it also represents an important milestone of product offering addressing both datacom and telecom needs. Since Q2 2022, the XY5424 product family has gone through DVT, 500-hour reliability testing, customer evaluation, and small batch shipments.

     Xinyun Tech’s complete IC and OSA solutions significantly simplify the design of miniaturized high-density pluggable modules. With the optimization of other key processes, these complete solutions can greatly enhance product performance, improve reliability, and reduce the overall module power consumption, PCB size and cost. This series of CDR products can greatly minimize the effects of signal jitter in the communication links. The extensive customer testing and verification demonstrate that the CDR product family of XinYun Tech outperforms the mainstream competing products in key areas. In addition, in terms of product experience, Xinyun Tech’s complete IC and OSA solutions substantially simplify the module development and assembly process, provide greater flexibility to meet application and operational needs, help customers further reduce costs, and achieve performance upgrades and user-friendliness. On the whole, XinYun Tech’s CDR product family is an ideal chipset solution for COB optical modules for 100G LR4/CWDM4/PSM4 & SR4 applications.
