SerDes芯片,纳芯微强势杀入
半导体行业观察· 2025-05-20 01:04
Core Viewpoint - The automotive industry is experiencing a dual transformation of electrification and intelligence, with smart cockpits and smart driving as key development routes. The integration of advanced technologies, including high-definition screens and various sensors, is enhancing user experience in vehicles. A critical component in this evolution is the in-vehicle SerDes technology, which is becoming increasingly important [1][2]. Summary by Sections Section 1: Overview of SerDes Technology - SerDes, short for Serializer Deserializer, is an electronic circuit that converts serial data to parallel data and vice versa. It consists of a serializer that converts parallel data into serial data and a deserializer that performs the reverse operation. The demand for SerDes in the automotive sector is surging due to the rapid development of smart cockpits and smart driving technologies [2][3]. Section 2: Market Dynamics and Challenges - The market for in-vehicle SerDes is currently dominated by overseas companies like TI and ADI, which have established high barriers to entry through proprietary protocols. The FPD-Link standard, created in 1996, and GMSL, introduced in 2008, are examples of technologies that have shaped the competitive landscape in automotive camera signal transmission [3][4]. Section 3: Challenges Faced by Domestic Manufacturers - Domestic manufacturers face significant challenges, including the lack of supply chain flexibility due to the proprietary nature of mainstream SerDes protocols. The current mainstream rates for SerDes range from 1 Gbps to 6.4 Gbps, with future upgrades expected to increase these rates, posing additional technical challenges [4][5]. Section 4: Advantages of Domestic Players - Domestic company Naxin Micro has several advantages in the SerDes market, including a mature automotive regulatory system, a fully domestic supply chain, and a comprehensive product offering that supports both electrification and intelligence in vehicles. Naxin Micro is focusing on the HSMT protocol to enter the SerDes market [7][8]. Section 5: HSMT Protocol and Competitive Edge - The HSMT protocol, promoted by domestic manufacturers, offers advantages over other protocols like MIPI A-PHY, including better error correction capabilities and support for physical layer retransmission. This protocol is gaining traction among domestic automakers, enhancing Naxin Micro's confidence in the market [10][11]. Section 6: Product Launch and Features - Naxin Micro has launched its first automotive-grade SerDes chip set, including the NLS9116 serializer and NLS9246 deserializer, designed for high-speed data transmission in ADAS and smart cockpit systems. These chips feature enhanced performance metrics, including a 100% improvement in receiver tolerance compared to international competitors [13][15]. Section 7: Future Outlook - Naxin Micro plans to expand its product offerings to cover a range of speeds and applications, including future developments in PAM-4 technology for higher data rates. The company aims to address the growing demand in the automotive sector while also considering applications in security and robotics [17][21].
