Description: USB接口2.0和1.1又什么区别。USB目前支持三种传输速度：低速的1.5Mbps、全速的12Mbps、高速的480Mbps，USB1.1的固定连结端口可以连接所有速度的周边，但当高速的装置连结在USB1.1连结埠上时，仅能表现出12Mbps的速度。USB2.0的固定连结端口可以连结三种速度的周边装置，并确保所有USB应用硬件间的兼容性-USB interface 2.0 and 1.1 What is the difference between also. USB currently supports three speeds: low speed of 1.5Mbps, full speed of 12Mbps, high-speed 480Mbps, USB1.1 fixed link port can connect all the speed of surrounding, but when the high-speed devices that link up at USB1.1 ports, the only show the speed of 12Mbps. Fixed link USB2.0 port can link the three speed peripherals, and to ensure that all USB applications between hardware compatibility

Description: High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support.
For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled
in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB
signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0
signaling running at hundreds of MHz, the existing design methodology must change.

Description: EDGE, the fastest transmission standard currently in use in GSM networks, is creating brand new opportunities for computing applications.
The MC75 from Siemens enables you to make use of this speed in your own products, facilitating multimedia downloads and data
streaming, for example.
EDGE, which stands for “Enhanced Data rates for GSM Evolution” is both a supplement and an alternative to UMTS. By employing this
standard, your products will be able to transmit data at very high speed, even in regions where UMTS is not available. In addition, due
to the Quad-Band technology, the module can be used in every GSM network worldwide. The MC75 includes an RIL driver, which makes
it particularly attractive for Microsoft © Windows Mobile™ based devices like smartphones and PDAs. The integrated USB port also
allows the use of the MC75 in applications like GSM/GPRS modems.-EDGE, the fastest transmission standard currently in use in GSM networks, is creating brand new opportunities for computing applications.
