Preface
With the continuous popularization of USB4, Thunderbolt 5, PCIE4.0 and other high-speed transmission technologies, the data transmission rate is getting faster and faster, which brings the problem of long-distance transmission loss.
Due to the excellent characteristics of the Retimer chip, it is especially suitable for lightning data cables, computer motherboards, server motherboards and other scenarios, effectively solving the problems of uneven signal timing, large loss and poor integrity when transmitting data over long distances. So which products are equipped with Retimer chips? For this reason, the charging head has sorted out three products with built-in chips, please follow the editor to take a look.
The application of Retimer chip in USB high-speed transmission
Xiangshuo ASM1562
Xiangshuo ASM1562 is a single-channel, dual-differential channel USB3.1 Gen2 Retimer chip, built-in signal interface up to 10Gbps, following USB3.1 specification, supporting USB3.1 Gen1 and Gen2, which can be used to enhance signal integrity and improve compatibility, suitable for long PCB lines or long-distance cable applications. The ASM1562 is available in a QFN-24 package, RoHS compliant, and operates at 1.8V.
Application examples

Intel JHL7040
Intel JHL7040 ReTimer chip is used for signal reconstruction, reducing signal jitter, improving the quality and stability of lightning signal transmission, and supporting Thunderbolt 4 high-speed cable applications.
Application examples
Apple 1.8m Thunderbolt 4 Pro data cable
Apple's Thunderbolt 4 Pro cable is made of black braided jacket, and the cable is thick and strong, which is more resistant to dirt and durability than other Apple cables. In addition, the new cable is available in 1.8 m and 3 m lengths, which can better meet different user groups.

Summary of the charging head network
The latest USB4 2.0 and Thunderbolt 5 high-speed communication standards support data transfer speeds of up to 80Gbps, making them ideal for connecting computers, peripherals and displays. However, high-speed communication standards are often limited by signal timing jitter and transmission distance, which requires special electronic components to solve.
The ReTimer chip can effectively complete the signal retiming and extend the transmission distance. Whether it's a USB4\Thunderbolt cable or a PC motherboard, the Retimer chip can be used to regenerate and repair the transmitted signal to ensure signal quality. Compared with the Retime chip, it is more stable and higher in long-distance transmission signal quality, which helps to reduce signal timing jitter while maintaining data integrity, especially suitable for long-distance transmission or scenarios with extremely high requirements for transmission rate.
