Description

technical field [0001] The invention relates to a circuit for realizing communication of a wireless network card interface, in particular to a circuit design for realizing communication with a PCMCIA wireless network card interface by using a programmable logic device CPLD. Background technique [0002] With the improvement of office conditions and the development of large-scale integrated circuit technology, various notebook computers have been widely used because of their convenient portability and flexible use. The same as the USB interface, the PCMCIA interface is one of the necessary interfaces for almost all notebook computers. Its main function is to insert a PCMCIA wireless network card to support its random access to the wireless local area network. [0003] At present, the wireless local area network (WLAN for short) based on the 802.11 protocol technology is mainly used, and the wireless channel is used as the data file transmission medium. For the application of...
