preface
In the early morning of September 13, 2023 (Beijing Time), Apple officially released the iPhone 15 series mobile phones and the new generation of Apple Watch.
![]()
Among them, The biggest upgrade of the iPhone 15 series mobile phones is that all the series use the USB-C interface. According to the latest news, The entire iPhone 15 series is equipped with a "completely standard" USB - C port, which has no restrictions on wires and accessories. Because A17 Pro chip integrates USB controller, The interface of iPhone 15 Pro series supports USB 3 transmission, and the speed can reach 10Gb/s. The standard version of iPhone 15 only supports USB 2, with the highest speed of 480Mb/s.
After the iPhone 15 uses the USB-C interface, it is expected to increase the transmission rate to the USB-IF high-speed transmission specification, so as to meet the iPhone 15 video transmission, data transmission, high-definition audio and other applications. At this rate, the cable needs to be equipped with an E-Marker chip to mark the cable's data transmission capability, so that the cable will not become a bottleneck and affect high-speed data transmission.
Two new iPhones support USB-C high-speed transmission
The iPhone 15 Pro Max can also connect the external hard disk through the full function data cable of USB 4. At present, the 16TB mobile hard disk can be recognized and read normally in testing, without picking up wires and hard disk.

What are the eggs of this generation of iPhone 15? Let's check them one by one.
IPhone15 Pro/Pro Max supports high-speed data transmission
The convenience of USB-C through, Apple's newly released iPhone 15 series has all been replaced with USB-C interface.

The iPhone 15 series includes two standard models and two Pro models. The difference in the USB interface protocol is that the standard model is equipped with USB 2.0, with a maximum transmission rate of 480Mbps, while the Pro model uses Apple's second-generation ultra wideband chip and USB-C port, supporting the USB 3 protocol, with a maximum transmission rate of 10Gbps, 20 times the former.

Support 4K 60 frame HD video capture
This is also one of the major upgrades of the new machine this year, The iPhone 15 Pro and iPhone 15 Pro Max can record 4K 60 frames of video directly with an external hard disk and store them directly in an external device. They can really be used as authoring devices.
In addition, Whether iPhone15 Pro and iPhone15 Pro Max can connect to the USB-C port of 2K and 4K external displays through the USB4 cable is still to be measured. However, previous iPhones already support lighting to HDMI output. This generation of iPhone15 has strong performance and is expected to bring more surprises.
Mobile phone built-in ReTimer signal enhancement chip
Previously, the charging head network introduced the interface form of iPhone 15 A mysterious IC can be seen vaguely from the rear of the USB-C mother seat of the small tail board. When you zoom in, you can see that this IC is a ReTimer chip. It can be inferred that many iPhone 15 series models support high-speed data transmission. This chip is used to amplify and enhance USB-C data transmission signals.
ReTimer chip is mainly used for signal reconstruction to reduce signal jitter, This ReTimer chip is often simple on the lightning/USB4 high-speed equipment disassembled from the charging head network It can improve the signal transmission stability of the high bandwidth data interface and achieve a longer transmission distance.

Advantages of USB4 full function cable
In September 2019, USB4 was officially released, with a maximum transmission rate of 40Gbps, the same as Thunderbolt 3. The USB4 has two specifications, namely the USB4 40 with a maximum bandwidth of 40Gbps and the USB4 20 with a maximum bandwidth of 20Gbps. Consumers need to understand that the USB4 40 is the full blood interface.

Currently, M1 The Apple MacBook on the M2 processor supports USB4 data transmission. MacBook is one of the three pieces of Apple and a representative of productivity tools. Through the USB4 data cable, the iPhone 15 Pro/Pro Max can be connected to the MacBook, realizing high-speed transmission of data, video and other materials, greatly reducing time and improving office efficiency.
In addition, the USB4 charging cable on the market also supports 140W or 240W fast charging, which can be used for super fast charging of MacBook. In this way, just one USB4 data cable can be used to send iPhone 15 AirPods Pro (USB-C version) IPad (USB-C version) MacBook is used at the same time, which is really a first-line connection.
USB4 chip
With the continuous progress and development of USB technology, USB4 brings users faster data transmission speed and higher power output. To experience the speed and convenience of USB4, a cable with an E-Marker chip is essential. This is because USB-IF has set a hardware threshold. If you want to support 5A high current, USB3.0 or higher transmission speed, and video output function, you need the support of E-Marker chip.
The full name of E-Marker is "Electronically Marked Cable", which can be understood as the electronic identity tag of USB Type-C cable. This chip can read various attributes of the cable, including power transmission capability, data transmission capability, video transmission capability, ID and other information. Based on this, the output terminal (such as charging head, notebook) can adjust the matching voltage/current or audio/video signal according to the device connected to the output terminal (such as mobile phone or monitor).
E-Marker chips also have different grades. Some only support video output, some only support USB 3.1 Gen1 or USB 3.1 Gen2, and some only support 5A current transmission. Such E-Marker chips that only support a special function belong to the lower end. The charging head network has summarized 12 E-Marker chips from seven major manufacturers that support USB4 PD3.1, which can meet the needs of high power transmission and 40Gbps high-speed data transmission cables.

The new cable specification has brought about the upgrade of the E-Marker chip. According to the charging head network, Yichong, Yuqun, Huinengtai, Hanxinwei, Infineon, Yingjixin Qinheng The manufacturer launched the USB PD3.1 fast charging standard, supporting USB4 E-Marker core Film.
Ranking is arranged according to the first letter of English.

Summary of charging head network
Since Apple's iPhone 15 series began to use the USB-C interface in an all-round way, almost all smart mobile devices on the market now use the USB-C interface. Users only need to carry a USB-C cable to power all devices and transmit data, instead of carrying multiple cables.
The release of USB4 has brought users faster data transmission speed and higher power output. High power, high-speed data transmission will be popular on more devices, and corresponding cables need to use more E-Marker chips. The charging head network has summarized the E-Marker chips supporting PD3.1 launched by seven chip manufacturers, which can meet the needs of 240W power transmission and 40Gbps high-speed data transmission cables.
The E-Marker chips launched by the original manufacturer of these chips have their own characteristics.
