I-PEX 82687-100B-01-D CABLINE®-VS 40AWG/50Ω series ultra-thin coaxial cable replacement

MIPI high-speed signal wiring, why is there an increasing focus on extremely thin coaxial cables?

In smartphones, industrial cameras, machine vision, AI cameras, AR/VR, and various embedded vision devices, the MIPI interface undertakes a large number of high-speed data transmission tasks between cameras, display modules, and main control chips. With the continuous increase in camera pixel count, frame rate, and data bandwidth, MIPI signals have higher requirements for the impedance consistency of cables, crosstalk control, signal loss, and structural dimensions. How to select ultra-fine coaxial cables for MIPI signals? For engineers, the first thing is not to only look at whether the wire diameter is sufficiently fine, but to make a comprehensive judgment based on the MIPI interface speed, channel count, transmission distance, internal space of the device, and signal integrity requirements. Ultra-fine coaxial cables, through independent shielding structures, can better control the high-speed signal transmission environment, and at the same time, have high flexibility, small size, and are suitable for high-density wiring, making them particularly suitable for internal connections in camera modules, display modules, and compact high-speed electronic devices.

I-PEX 82687-100B-01-D: 30Pin ultra-thin coaxial cable assembly for high-density internal connections

This introduced I-PEX 82687-100B-01-D corresponds to the CABLINE®-VS 30P HARNESS. The engineering drawing uses 30 AWG#40, 50Ω Micro-Coaxial Cables, with the finished length of 100.0±5.0mm. The wire position is defined as 1-1, meaning a direct connection is made between the corresponding Pins at both ends. The harness uses a wire end connector component model of 20454-230T, corresponding to a high-density connection structure with 30 Pins and a 0.5mm pitch. For MIPI applications, 30 high-speed signal connections can provide a compact internal connection solution for multi-channel data transmission, while the AWG#40 extremely fine coaxial cable can achieve high-density wiring within limited device space. When engineers are selecting products, they should pay special attention to 50Ω impedance, harness length, Pin definition, and connector matching; purchasers should also take these parameters as complete technical conditions when inquiring for quotes or importing alternative suppliers, rather than simply replacing it with a "30Pin extremely fine coaxial cable harness."

Select ultra-fine coaxial cables for MIPI signal, the length, impedance, and connector must be considered together

MIPI high-speed signals are not about "the thinner the better" or "the shorter the better," what is truly important is the matching and consistency of the entire high-speed link. As the cable length increases, the signal propagation delay and high-frequency loss will change accordingly; if there is a significant length difference between multiple MIPI channels, it may also cause inter-channel delay deviation, thus compressing the system timing margin. Therefore, specifications like I-PEX 82687-100B-01-D with a 100±5mm specification should try to maintain the original length and structure when replacing them for compatibility. If the device indeed needs to change the length, it is recommended to revalidate the signal integrity such as impedance, insertion loss, return loss, crosstalk, and skew. At the same time, connectors are also an important part of the high-speed link, specifications like 20454-230T, 30Pin, 0.5mm Pitch need to be accurately matched with the device interface. Only when the wire, connector, length, wiring sequence, and termination process meet the requirements together can the risk of attenuation, reflection, crosstalk, and data anomalies in the actual application of MIPI high-speed signals be reduced.

Selection, compatibility, and alternative solution references and recommendations

For engineers and purchasers who need to replace the domestic I-PEX 82687-100B-01-D, it is recommended to first confirm the connector series according to the actual interface of the device, and then check the key parameters such as 20454-230T, 30Pin, 0.5mm Pitch, AWG#40, 50Ω, 100±5mm, and 1-1 line position; if applied to MIPI camera or machine vision equipment, signal integrity verification should also be carried out according to the actual MIPI rate and channel number. It should be especially noted that different CABLINE series of I-PEX have differences in connector structure, mating method, and application specifications, and cannot be replaced directly just by the same number of pins. Our company specializes in the production and manufacturing of extremely fine coaxial cable assemblies, and can carry out compatibility development according to the original cable assembly, product material number, engineering drawings, and equipment interface requirements provided by customers. Our company can provide I-PEX 82687-100B-01-D compatible and alternative cable assembly solutions, and can provide corresponding extremely fine coaxial cable assembly customization and domestic alternative support around MIPI camera, industrial camera, machine vision, high-speed display and other applications.

The core of MIPI routing is not "the finer, the better," but the overall matching of the high-speed link.

For MIPI high-speed signals, the value of extremely thin coaxial cable bundles lies in their ability to balance high-density wiring, signal isolation, impedance control, and flexible connections within limited space. Taking the I-PEX 82687-100B-01-D as an example, its complete product specifications are composed of 30 pins, 0.5mm pitch, 20454-230T, AWG#40, 50Ω, 100±5mm, and 1-1 line position. Engineers should comprehensively evaluate factors such as interface speed, transmission distance, cable length, channel consistency, and connector matching when designing MIPI cable bundles; purchasing personnel should consider these parameters as important bases for technical audit of alternative suppliers, rather than just comparing unit price and appearance.
