摘要: 研究高速系统级封装(SiP)处理芯片对现代高速数据处理领域发展具有重要的应用价值。针对目前高速处理系统普遍存在通道数少、集成度低、占用面积大和易受干扰等问题,提出以现场可编程门阵列(FPGA)为核心、集8路采集和8路输出为一体、支持电子器件工程联合委员会标准204B(JESD204B)标准化串行接口传输的高速SiP处理芯片方案。其内部的模数转换器(ADC)与数模转换器(DAC)均为高速采集芯片,支持JESD204B接口协议,串行器速率最高可达10 Gbit/s,能够实现数据的快速传输和信号的高效处理。深入分析该SiP处理芯片的架构组成以及性能参数,实测封装面积为20.25 cm²,通道隔离度约75 dB。同时,提出一种时钟芯片外挂的架构策略,有效提高芯片的耐高温性能,进一步拓展同类高速SiP芯片的应用场景及适用环境。

Abstract: Research on high-speed system-in-package (SiP) processing chips is of significant practical application value for the development of the modern high-speed data processing field. To address the common issues in current high-speed processing systems, such as a small number of channels, low integration, large occupied area, and high susceptibility to interference, a high-speed SiP processing chip scheme is proposed. This scheme takes the field-programmable gate array (FPGA) as the core, integrates 8-channel acquisition and 8-channel output, and supports the transmission of the standardized serial interface specified in the Joint Electron Device Engineering Council (JEDEC) Standard 204B (JESD204B). The internal analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) of the chip are all high-speed acquisition chips, which support the JESD204B interface protocol. The serializer rate can reach up to 10 Gbit/s, enabling fast data transmission and efficient signal processing. The architectural composition and performance parameters of this SiP processing chip are analyzed in depth. Practical measurements show that the package area is 20.25 cm², and the channel isolation is about 75 dB. Meanwhile, an architectural strategy with an external clock chip is proposed, which effectively improves the high-temperature resistance of the chip and further expands the application scenarios and applicable environments of similar high-speed SiP chips.
