?2000 - 2001 genesys logic inc. ? all rights reserved - 2 gl911 tx 1 . 1 1. overview gl901rx/GL911TX rf - usb is the high performance and low cost assp solution for wireless mouse application. genesys l ogic?s rf - usb mouse series support usb and ps2 interface and provide ultra high response for wheel sc rolling type mouse up to 100 packets per second. they are designed to support up to 4 dimension and 5 buttons to cover most of the pointing device applications. GL911TX is the mouse controller and rf transmitter encoder for portable wireless mouse body. t his chip is a high speed risc - like mcu can perform high tracking speed for wheel mouse moving and encode the mouse data with genesys logic?s proprietary protocol. GL911TX can support 2d/3d/4d and up to 5 buttons. with 4800bps high transmission rate it can report 2.5 times data rate than traditional tethered rs - 232 mouse and almost the same rate as general tethered ps2 or usb mouse. it means the overall excellent performance would give better mouse operation?s feeling just like the tethered mouse. gl901rx i s a bridge between rf demodulated base band signal to usb or ps/2 interface. it can adopt any rf wireless receiver easily and decode the rf genesys logic?s proprietary protocol to host site. this chip is also a high speed risc - like mcu with robust low spee d usb sie transceiver. with genesys l ogic?s proprietary wireless link protocol, which can distinguish up to 255 different id code to avoid other rf interference and insure the error - free data to host.
