Classification of data cables of USB interface
Without IC (central control chip); with IC (central control chip); special chip.
1, without IC (central control chip): there is no central control chip, it must be inserted into the mobile computer to recognize the line, the price is cheap.
Typical models: Samsung CDMA series, D500 series; Motorola E398 series, V3 series; NOKIA DKU-2; NEC N720 series; SIEMENS 65 series and so on.
2, with IC: with the central control chip, the type of the common chip is 2303, 2101 and 3116, and it doesn't need to plug in the mobile phone. The price of a IC is 10 yuan, so the price is more expensive than that without IC. The working principle of the data line with the chip is the USB to COM, which converts the USB interface into a serial port to display on the computer.
Typical models: Samsung E638 series, D418 series, NEC N610 series, SIEMENS 25 series, 55 series, Sony Ericsson mobile data line, Panasonic mobile data line, lenovo mobile data line and so on.
3, special chip: non ordinary popular chip, special special type of chip such as DKU-5, CA-42, DCU-11 and so on.
Note: we do not think that the quality of the IC with good quality, without the poor quality of IC, the actual belt without IC is based on the suitable model of the production of mobile phones.
