cell phone jammer only has shielding of the cell phone.
According to their figures will be able to know is what kind of circuit functions. The prefix of the IC product model for the company code, such as: AM-AMD, AT-ATMEL Corporation, MC-Motorola, X-

XICOR companies. Special letters omitted the prefix stands for the English of the plant such as Intel, integrated circuits, in general, usually will own production plant or company name, logo,

print up. Each product in the middle of the same number of models are generally interchangeable. It is customary (strict) title :: 74XX 74HCXX, 54XX, 40XX, 45XX, 28FXXX, 29LVXXX. If the circuit is

more stringent component requirements, it is necessary to analyze the information provided by the manufacturer to make a decision. It is the notes and attentions of cell phone jammer .
The character of the V998 and V60 mobile phones is 16, the data bus width is 16, from low to high, respectively, D0, D1, ? ? ? ? ? ?, D14 and D15. Phone 16 `font for each word line corresponding to

the storage unit 16, which is 16 bits, two bytes. I2 bus is in English Inter Integrated Circuit Busde abbreviation, often translated into an internal IC bus, or inter-IC bus is a communication of

the Dutch company Philips patented technology, it can be composed by two lines (serial data line and serial clock line) enables all devices on the bus for data transfer, I2 bus addressing ways to

use the software to identify the articulated bus of each I2C bus, each of the I2C has a CD one to determine the address number, so that the data transfer between devices, the I2C bus is almost

omitted the connection of the chip select address decoding. cell phone jammer has effective shielding of such cell phone signals as GSM900, DCS1800, PCS1900, CDMA and PHS and so on.
The basic structure of the I2C bus system. The I2C bus is a two-wire bidirectional serial bus, I2C bus system, the bus is only two lines. One called Serial Clock Line (Senal Clck Line) commonly

used in SCL, the other is called the serial data (Serial Data Line) commonly SDA indicated that they are from the CPU to bring out other cell circuit hanging of two I2C bus, the CPU has control of

the bus, also known as the main controller, the other circuits are controlled by the CPU, so they are collectively referred to as a controller. The master can be sent to the bus clock signal, but

also actively to the bus to send data signals and receive the response signal of the controller sent controller does not have the ability of the clock signal is sent. The user can program through

the micro-computer setter by himself/herself when using cell phone jammer .
