In mobile phones, tablets, laptops, camera module, AI vision equipment, and other products, the MIPI interface is responsible for high-speed data transmission tasks. For such high-speed differential signals, the choice of extremely thin coaxial cables cannot be determined solely by "whether the wire is thin enough," but it also needs to comprehensively consider impedance, wire diameter, shielding structure, length, attenuation, crosstalk, and connector matching. The I-PEX CABLINE®-SS is an extremely thin coaxial cable connector with a 0.4mm pitch, featuring vertical right-angle insertion and extraction, and horizontal cable exit structure. The official documentation lists the MIPI standard as part of its applicable standard reference range, while also providing Micro-Coaxial Cable AWG36, AWG38, AWG40, and AWG42 specifications. For devices that need to balance high-speed transmission and internal space, extremely thin coaxial cables can complete multi-channel high-speed signal connections within a limited space.
When selecting extremely thin coaxial cables for MIPI high-speed signals, AWG is not the smaller, the better, nor the thinner, the better. It should be determined comprehensively based on signal rate, transmission distance, equipment space, and impedance requirements. AWG 40 has a good balance between conductor size, cable flexibility, and high-speed transmission requirements. The official high-speed performance verification of I-PEX CABLINE®-SS also uses AWG #40, 45Ω, 100mm Micro-Coaxial Cable for testing and lists MIPI as one of the applicable standard references. It should be noted that the high-speed test conditions on the official page are not completely the same as the specific product cable diagram parameters, so in actual projects, the target cable diagram, MIPI interface specifications, and whole machine SI test results should still be used as the final basis. For I-PEX 82884-100B-02-D, it corresponds to CABLINE®-SS 20P, Micro-Coaxial 40AWG, 300mm, 1-N cable; therefore, when carrying out alternative development, it cannot be simply replaced with other AWG specification coaxial cables, but should maintain the original cable material structure and electrical characteristics.
From the perspective of engineers and purchasing staff, confirming a MIPI ultra-thin coaxial cable assembly first requires verifying the consistency of material number, pin count, length, wire diameter, and wire position definition. The I-PEX 82884-100B-02-D belongs to the CABLINE®-SS 20P, 300mm, 1-N Micro-Coaxial 40AWG cable assembly, using the connector model 20373-R20T-06 at the cable material end with wire position defined as 1-N. The official I-PEX model data sheet also explicitly lists the 82884 model corresponding to 20P, 300mm, 1-N for MIPI applications. For MIPI applications, it is also necessary to further confirm the impedance control of high-speed differential channels, consistency of cable length, shielding continuity, and connector contact reliability. If the internal space of the device requires passing through a pivot or narrow structure, the narrow design of CABLINE®-SS itself also needs to be verified together with the actual routing space; the official product data sheet states a combined height of 1.65±0.2mm and a Depth of 3mm.
For projects requiring replacement of I-PEX 82884-100B-02-D, it is recommended that the engineering end first confirm key parameters such as 20P, Micro-Coaxial AWG40, 300mm, 1-N, 20373-R20T-06 according to the original drawings, and then verify signal integrity based on the actual MIPI rate and device structure. The procurement end should also avoid providing only the condition "CABLINE-SS 20P" when inquiring for quotes, but should clearly specify the complete material number and key technical requirements, as I-PEX officially also provides 20P models with 100mm, 200mm, and 300mm lengths, 1-N type, and there are also different products with 1-1 wire sequence, and the model cannot be judged solely by the number of pins. During the replacement development process, it is also necessary to verify the connector compatibility, wire impedance, insertion loss, crosstalk, wire sequence, length tolerance, and product reliability. Our company can provide: I-PEX 82884-100B-02-D compatible replacement cable harness solutions, which can confirm specifications, develop samples, and manufacture batch production of 20P ultra-fine coaxial cable harnesses based on the customer's original drawings and actual application requirements.
The core of MIPI routing is "high-speed performance + structural compatibility" with synchronous consideration.
When selecting a very thin coaxial cable for MIPI signal, what truly needs to be paid attention to is not just the single AWG wire diameter, but the complete high-speed transmission link composed of wire material, impedance, length, shielding, wire sequence, and connector. I-PEX CABLINE®-SS has specifications with various pin numbers such as 0.4mm Pitch and 20P, and lists MIPI as an applicable standard reference; among them, 82884-100B-02-D corresponds to 20P, 300mm, Micro-Coaxial 40AWG, 1-N cable assembly, with a matching cable end connector of 20373-R20T-06.
