First statement: you don't mistakenly take IC headphone cables are of good quality and poor quality of headphone cables without IC, with or without actual IC is production according to the application of the mobile phone models. So how do you distinguish between with IC and without IC phone data line? Small make up today for everyone to look at the: a, cell phone data cable with IC: take the central control chip, the common chip models for 2303, 2101, 3116, without mobile computer will recognize line, because a IC price is 10 yuan, so the price is expensive than that of without IC. Working principle of the cable is the USB to COM with chip, the USB interface is transformed into a serial port on the computer display. Typical models: samsung E638 series, the series of D418; NEC N610 series; Siemens 25 series, 55 series; SONY Ericsson mobile phone data cable; Panasonic headphone cables; Lenovo mobile data line, and so on. Headphone cables without IC: have no central control chip, must plug in mobile computers to recognize line, the price is cheap. Typical models: samsung CDMA series, D500 series; MOTOROLA mot E398 series, the series of the V3; Nokia DKU - 2; NEC N720 series; Siemens 65 series and so on. Finally have to tell you one thing: with IC and without IC is not important, actually choose the right cell phone cable is important.
