Apple's newly launched 240W USB-C charging cable is USB2.0 specification, and the cable length is about 2 meters. Since it has a built-in E-Marker chip to mark the cable's capabilities, this charging

Apple officially released the iPhone 15 series of mobile phones and a new generation of Apple Watch.

Among them, the biggest upgrade of the iPhone 15 series is that the entire series uses USB-C interfaces. According to the latest news, the entire iPhone 15 series is equipped with "completely standard" USB-C ports, without any restrictions on wires and accessories. . Since the A17 Pro chip integrates a USB controller, the interface of the iPhone 15 Pro series supports USB 3 transmission, with a rate of up to 10Gb/s, while the standard version of the iPhone 15 only supports USB 2, with a maximum rate of 480Mb/s.

After the iPhone 15 switches to the USB-C interface, it is expected to increase the transmission rate to the USB-IF high-speed transmission specification to meet the requirements of iPhone 15 video transmission, data transfer, high-definition audio and other applications. This rate requires a built-in E-Marker chip in the cable. To mark the data transmission capacity of the cable, so that the cable will not become a bottleneck and affect the high-speed transmission of data.

Two new iPhones support USB-C high-speed transmission

The iPhone 15 Pro Max can also connect to an external hard drive through a USB 4 full-function data cable. Currently, the 16TB mobile hard drive in testing can be recognized and read normally without having to choose between wires and hard drives.

What are the Easter eggs in this new generation of iPhone 15? Let Charging Head Network take stock of them one by one below.

iPhone15 Pro/Pro Max supports high-speed data transmission

With the convenience of USB-C pass-through, Apple’s newly released iPhone 15 series has all been equipped with USB-C interfaces.

Thanks to USB 3 support, videos captured on iPhone can be stored directly to an external hard drive.

The iPhone15 series includes two standard version models and two Pro version models. There are differences in USB interface protocols. The standard version model is equipped with USB 2.0 with a maximum transmission rate of 480Mbps, while the Pro version model uses Apple’s The second-generation ultra-wideband chip and USB-C port support the USB 3 protocol, and the transmission rate can reach up to 10Gbps, which is 20 times higher than the former.

Support 4K 60-frame HD video shooting

This is also one of the major upgrades of this year’s new phones. iPhone15 Pro and iPhone15Pro Max can directly connect external hard drives to record 4K 60-frame videos and store them directly in external devices. They can truly be used as creative devices.

In addition, whether iPhone15 Pro and iPhone15Pro Max can achieve one-line connection to the USB-C port of 2K and 4K external monitors through USB4 cables has yet to be tested. However, previous iPhones have supported lightning to HDMI output, and this generation of iPhone 15 has strong performance and is expected to bring more surprises.

Mobile phone built-in ReTimer signal enhancement chip

Previously, Charging Head Network introduced the interface form of iPhone 15. A mysterious IC can be seen faintly behind the USB-C female socket of the small board plugged into it from the end. If you zoom in, you can see that the IC is a ReTimer chip. It can be inferred that many models of the iPhone 15 series support high-speed data transmission. This chip is used to amplify and enhance USB-C data transmission signals.

The main function of the ReTimer chip is to reconstruct signals and reduce signal jitter. This ReTimer chip is often found on Thunderbolt/USB4 high-speed devices that have been disassembled by the charging head network. It can improve the signal transmission stability of high-bandwidth data interfaces and achieve better performance. Long transmission distance.

Advantages of USB4 full-featured cable

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

Currently, Apple MacBooks using M1 and M2 processors support USB4 data transmission. MacBook is one of Apple's three-piece set and a representative of productivity tools. Through the USB4 data cable, iPhone15 Pro/Pro Max can be connected to MacBook to realize high-speed transmission of data, video and other materials, greatly shortening time and improving office efficiency.

Not only that, the USB4 charging cables on the market also support 140W or 240W fast charging, which can be used for super fast charging of MacBook. In this way, when you go out, you only need one USB4 data cable to use it with iPhone 15, AirPods Pro (USB-C version), iPad (USB-C version), and MacBook at the same time. It can be said to be a real one-line connection.

USB4 chip

With the continuous advancement and development of USB technology, USB4 has brought faster data transmission speed and higher power output to users. If you want to experience the speed and convenience brought by USB4, a USB with E-Marker chip Cables are essential. This is because USB-IF sets a hardware threshold. If you want to support 5A high current, support USB3.0 or higher transmission speed, and support video output function, you need the support of E-Marker chip.

The full name of E-Marker is "Electronically Marked Cable". We can understand it as the electronic identity tag of the USB Type-C cable. Through this chip, various attributes of the cable can be read, including power transmission capability, data Transmission capabilities, video transmission capabilities, ID and other information. Based on this, the output end (such as charging head, notebook) can adjust the matching voltage/current or audio and video signal according to the device connected to the output end (such as mobile phone or monitor).

E-Marker chips themselves also have different grades. Some only support video output, some only support USB 3.1 Gen1 or USB3.1 Gen2, and some only support 5A current transmission. These E-Marker chips that only support one special function are lower-end. 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, it has been launched by manufacturers such as Yichong, Yuqun, Huinengtai, Hanxin Micro, Infineon, Yingjixin, and Qinheng. It complies with the USB PD3.1 fast charging standard and supports the USB4 E-Marker chip.
