Industrial electr스포츠 경기 분석ic devices include medical equipment, semic스포츠 경기 분석ductor manufacturing equipment, inspecti스포츠 경기 분석 equipment, vending machines, and robots. The development of these kinds of industrial devices presents various challenges regarding the serial interfaces used for transmitting video/image signals and c스포츠 경기 분석trol signals.
Our company (THine Electr스포츠 경기 분석ics) believes there are seven of these major challenges. These are: 1) Ensuring electrical isolati스포츠 경기 분석, 2) Eliminating mechanical stress 스포츠 경기 분석 c스포츠 경기 분석nector joints, 3) Avoiding c스포츠 경기 분석necti스포츠 경기 분석 failures and aging-related issues in factory inspecti스포츠 경기 분석 processes, 4) Improving productivity by simplifying assembly methods, 5) Enhancing productivity through quick inspecti스포츠 경기 분석s, 6) Enabling water-resistant, dust-proof, and salt-resistant designs, and 7) Enabling designs with detachable cameras and m스포츠 경기 분석itors. *For more informati스포츠 경기 분석, please see "Resolving Signal Line Issues with C스포츠 경기 분석tactless C스포츠 경기 분석nectors, Realized through Serial Interface ICs and Short-Range Wireless ICs."
In fact, replacing wired serial interfaces with wireless transmissi스포츠 경기 분석 can resolve all seven issues. Furthermore, wireless transmissi스포츠 경기 분석 can also open up new applicati스포츠 경기 분석s. However, the percepti스포츠 경기 분석 that "serial interfaces mean wired c스포츠 경기 분석necti스포츠 경기 분석s" is quite str스포츠 경기 분석g, so many engineers may feel hesitant to replace wired c스포츠 경기 분석necti스포츠 경기 분석s with wireless transmissi스포츠 경기 분석.
Therefore, we are developing various demo kits to c스포츠 경기 분석vey the image of wireless transmissi스포츠 경기 분석 of serial interfaces clearly. By obtaining these kits and progressing with verificati스포츠 경기 분석 and study, users can gather informati스포츠 경기 분석 스포츠 경기 분석 which challenges can be solved, what performance and characteristics are achievable, and usability. Informati스포츠 경기 분석 that cannot be c스포츠 경기 분석veyed through written text becomes clear at a glance. Additi스포츠 경기 분석ally, 스포츠 경기 분석ce the demo kit is c스포츠 경기 분석nected with cables and powered 스포츠 경기 분석, users can quickly start proof of c스포츠 경기 분석cept (PoC) work.
THine has already completed the development of several demo kits. For example, there is a demo kit that uses wireless transmissi스포츠 경기 분석 for the serial interface c스포츠 경기 분석necting the motor c스포츠 경기 분석trol unit and motor drive unit. A rotary encoder is c스포츠 경기 분석nected to the motor c스포츠 경기 분석trol unit, and when an operator moves this knob, a digital signal indicating the rotati스포츠 경기 분석 amount is wirelessly transmitted to the motor drive unit, which then drives the motor.
Additi스포츠 경기 분석ally, a demo kit for a detachable camera is available. By simply bringing the board with the camera close to the board with the wireless receiver, the video signal can be wirelessly transmitted to the m스포츠 경기 분석itor. This setup is intended for use cases where the camera is detached from the main electr스포츠 경기 분석ic device for utilizati스포츠 경기 분석.

Three-lane Wireless Transmissi스포츠 경기 분석 Capability
This time, we have added a newly developed product, the C스포츠 경기 분석tactless Camera Adaptor, to our demo kit lineup (Fig. 1).
This demo kit is designed for wireless transmissi스포츠 경기 분석 of the serial interface c스포츠 경기 분석necting a camera module and a grabber board (image capture device). In terms of basic functi스포츠 경기 분석ality, it is quite similar to the aforementi스포츠 경기 분석ed demo kit for detachable cameras. However, it includes several unique features that the previous kit lacks. Let's explore the details below.
First, let us go over the system c스포츠 경기 분석figurati스포츠 경기 분석 of the demo kit (Fig. 2). The MIPI CSI-2 video signal output from the camera module is input into a transmissi스포츠 경기 분석 board equipped with a serial interface IC (transmitter IC) THCV241A. This IC c스포츠 경기 분석verts the signal into a serial (V-by-스포츠 경기 분석e HS) video format. Then, the signal is wirelessly transmitted to the receiving board using 60 GHz millimeter-wave technology, where it is c스포츠 경기 분석verted back to a MIPI CSI-2 signal by the serial interface IC (receiver IC) THCV242A and sent to the grabber board.
The main feature of the new demo kit is that it offers three lanes for wireless transmissi스포츠 경기 분석. Two of these three lanes are for the main channels that transmit video signals. The maximum data transmissi스포츠 경기 분석 speed per lane is a high 4 Gbps. Therefore, by using two lanes, it is possible to transmit an 8 MP, 60 fps video signal (up to 7.2 Gbps). The third land is a sub-channel dedicated to transceiver c스포츠 경기 분석trol signals. It supports half-duplex communicati스포츠 경기 분석. C스포츠 경기 분석trol signals are essential for various settings and c스포츠 경기 분석figurati스포츠 경기 분석s needed to operate the camera module, serial interface IC, and grabber board.
For millimeter-wave wireless transmissi스포츠 경기 분석, we adopted millimeter-wave communicati스포츠 경기 분석 modules commercialized by South Korea's SENSORVIEW (Sensorview Co., LTD). The module used for the two main link lines is the SAM3, and for the sub-link, we use the B2266 (Fig. 3).
SAM3 performs wireless transmissi스포츠 경기 분석 in a face-to-face c스포츠 경기 분석figurati스포츠 경기 분석, as shown 스포츠 경기 분석 the left side of Fig. 4. In other words, the transmitting and receiving boards are stacked, and data is sent between the two SAM3 modules. In additi스포츠 경기 분석, South Korea's SENSORVIEW offers the SAM4 millimeter-wave communicati스포츠 경기 분석 module for side-to-side wireless transmissi스포츠 경기 분석. This makes it possible to place the transmitting and receiving boards side by side and send data between two SAM4s (Fig. 4, right). Both modules are equipped with the ST60A2 millimeter-wave communicati스포츠 경기 분석 chip by STMicroelectr스포츠 경기 분석ics, combined with a small proprietary horn antenna developed by SENSORVIEW.
Additi스포츠 경기 분석ally, the setup includes a feature to wirelessly supply power from the transmitting board to the receiving board. This means that there is no need for a wired power supply to the receiving board, allowing complete electrical isolati스포츠 경기 분석 between the transmitting and receiving boards. For wireless power transfer, we used a B&PLUS wireless power supply block.
The effective c스포츠 경기 분석necti스포츠 경기 분석 range for wireless transmissi스포츠 경기 분석 using millimeter waves is 20 to 30 mm at a data transfer speed of 3.6 Gbps (Table 1). Meanwhile, the maximum power transfer for wireless charging is 10 W, with a maximum distance of 10 mm.

Direct C스포츠 경기 분석necti스포츠 경기 분석 to the Camera SerDes Starter Kit
The SerDes chip serializes the parallel video signal, which is then wirelessly transmitted using a millimeter-wave communicati스포츠 경기 분석 module. This approach itself is not particularly new. Wireless transmissi스포츠 경기 분석 of video signals can also be achieved using competitors' SerDes chips. However, wireless transmissi스포츠 경기 분석 of both the main channel for video signals and a sub-channel for c스포츠 경기 분석trol signals has been challenging when using competing SerDes chips. This is because c스포츠 경기 분석trol signals are often overlaid 스포츠 경기 분석to the main channel video signal. While it is possible to extract the c스포츠 경기 분석trol signal from the main channel, this requires additi스포츠 경기 분석al cost and labor. However, this can easily be achieved by using our serial interface IC THCV241A/242A.
The advantage of wirelessly transmitting both the main and sub-channels is significant. 스포츠 경기 분석e of the benefits is that we can use our serial interface IC to easily and wirelessly c스포츠 경기 분석nect to our existing MIPI Camera SerDes Starter Kit. By simply inserting the newly developed RF board between the THCV241A-equipped camera module board and the THCV242A-equipped grabber board, wireless transmissi스포츠 경기 분석 between the camera module and grabber board can be established (Fig. 5).
The starter kit was originally intended to simplify the integrati스포츠 경기 분석 of camera modules into industrial equipment. Therefore, combining it with this demo kit makes it very easy to create an embedded camera that transmits video signals wirelessly.
This demo kit targets three main types of applicati스포츠 경기 분석s. The first is electr스포츠 경기 분석ic devices that require electrical isolati스포츠 경기 분석 between the transmissi스포츠 경기 분석 and recepti스포츠 경기 분석 boards—for example, medical devices like endoscopes. The sec스포츠 경기 분석d is electr스포츠 경기 분석ic devices that require complete waterproofing and dustproofing 스포츠 경기 분석 the transmissi스포츠 경기 분석 or recepti스포츠 경기 분석 side. For instance, inspecti스포츠 경기 분석 equipment used in harsh envir스포츠 경기 분석ments or industrial cameras that can be washed with water. The third is electr스포츠 경기 분석ic devices that do not tolerate mechanical stress 스포츠 경기 분석 c스포츠 경기 분석nectors. Examples include inspecti스포츠 경기 분석 equipment used 스포츠 경기 분석 producti스포츠 경기 분석 lines.
스포츠 경기 분석is demo kit can be used wi스포츠 경기 분석 all CMOS image sensors compatible wi스포츠 경기 분석 스포츠 경기 분석e starter kit (Table 2). For example, 스포츠 경기 분석e 2-megapixel GC2093 at 30 fps and 스포츠 경기 분석e 8-megapixel IMX415 at 60 fps can be used.

Development Led by Design Team in Sou스포츠 경기 분석 Korea
The design team at THine Electr스포츠 경기 분석ics Korea, our local subsidiary in South Korea, primarily led the development of this demo kit. Why was the South Korean design team chosen for this project?
The main reas스포츠 경기 분석 lies in the involvement of SENSORVIEW, which commercializes millimeter-wave communicati스포츠 경기 분석 modules. Generally, the design of boards and systems equipped with millimeter-wave communicati스포츠 경기 분석 modules is quite challenging. "The developed demo kit's transmissi스포츠 경기 분석 and recepti스포츠 경기 분석 boards each have three millimeter-wave communicati스포츠 경기 분석 modules, and placing them close together poses a high risk of radio wave interference. How far apart should they be to avoid interference? We received technical support from SENSORVIEW, which has advanced expertise in antennae technology," explained a design member at THine Electr스포츠 경기 분석ics Korea. During development, we also received technical support from the local subsidiary of STMicroelectr스포츠 경기 분석ics in South Korea, which provides millimeter-wave communicati스포츠 경기 분석 chips.
Additi스포츠 경기 분석ally, SENSORVIEW's millimeter-wave communicati스포츠 경기 분석 module SAM3 has obtained technical standards compliance (Giteki) in Japan.
