the Realization of High-Speed Data Transmit Module Based on FX919B

It's a new data business to realize high-speed data transmission over broadcast channel by using traditional broadcast station.To complete this function must rely on the realization of wireless high-speed modem.This paper introduced the character of FX919B and choice of some parameter.It particularly narrated circuit design and programmer about the application of FX919B.This chip realized wireless data transmission of broadcast station through connecting station with audio interface and connecting microprocessor with parallel port.
