keyboard designs. The JB16 is specially designed for USB wireless
application. It has high processing power and large memory size to
handle overall data traffic control for multiple input devices.
1.4 Transmit and Receive
In data transmission, the data generated from the key matrix in a
keyboard or displacement detection/button status data in mouse
application is detected by MCU and sent to the baseband IC in a parallel
format. All kinds of media access, link layout control, and data
conversion in serial format are handled by the baseband IC. The final
data in serial format is transmitted by the RF module at 2.4 GHz.
In data reception, the data received from RF module is decoded with
corresponding protocol, and the serial packet data will be converted into
parallel format again in baseband processing. The final data in parallel
format will be captured by MCU and sent to the PC host through the USB
interface.
