The transmission is faster and more stable, and the message says that Apple iPhone 15 series introduces USB 4 retimer chip.

CTOnews.com, May 10 (Xinhua)-- Apple will launch the iPhone 15 series this fall. The biggest change is the port from Lightning to USB Type-C. According to the latest news, Apple has introduced the USB 4 retimer chip to achieve faster transmission speed and more stability.

It is reported that Apple has invited Perry Technology to assist in the development of USB 4 and plans to introduce timer (retimer) chips, which is expected to become a big selling point of the iPhone 15 series.

The data transfer speed of USB 4 is up to 40 Gbps, almost twice the speed of USB 3.0. This allows you to transfer large-volume files, such as 4K movies and graphics, in seconds. It is also an ideal technology for connecting multiple monitors and external video monitors.

CTOnews.com inquires relevant materials, with relevant information as follows:

Retimer is similar to a PHY chip. When the signal passes through the Retimer, the signal is reconstructed by the internal clock to increase the transmission energy of the signal, and then continue to transmit.

Retimer is an internal IC with CDR (data clock recovery). After data recovery, the signal is sent out according to the serial channel again, which can reduce the jitter of the signal.

Perry Technology has entered Apple's iPad and MacBook supply chain, and if it wins a new order from Apple and becomes a new member of the iPhone 15 series USB Type-C, it will undoubtedly greatly boost the company's performance.
