description avago technologies and chipcon have joined forces to produce a new wireless laser mouse reference design kit. based on the new avago technologies adns-6030 low power laser mouse sensor, chipcons radiodesk tm with CC2500 2.4ghz rf transceiver, and holtek semi - conductor ht82k68e and ht82k96e microcontrollers, this reference design kit provides a low cost, power ef - fcient and feature-rich solution in one neat package. the avago technologies adns-6030 low power laser mouse sensor, an 18-pin staggered dual inline pack - age (dip), is based on laserstream technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of move - ment. its high-performance, low power architecture is capable of sensing high-speed mouse motion while prolonging battery life, two performance areas essen - tial in demanding wireless applications. the adns-6030 sensor along with the adns-6120 or adns-6130-001 lens, adns-6230-001 clip and adnv- 6330 vcsel form a complete and compact laser mouse tracking system. there is no moving part, which means high reliability and less maintenance for the end user. in addition, precision optical alignment is not required, facilitating high volume assembly. adnk-6033-cc24 usb 2.4ghz rf wireless laser mouse designers kit product overview features ? complete wireless laser mouse reference design kit ? windows? 98se, windows 2000 and windows xp compatibility ? usb 1.1 low-speed compliance ? user identity code to avoid confict with other de - vices ? a high data rate 2.4ghz rf link ? transmission data rate of 250kbps ? 15 meters communication distance ? avago technologies new laserstream technology ? smooth surface navigation ? high speed motion detection up to 20ips and 8g ? 800cpi resolution ? self-adjusting power-saving modes for longest bat - tery life ? laser fault detect circuitry on-chip in the navigation sensor for eye safety compliance ? no mechanical moving parts ? minimal number of passive components ? high reliability
figure 1. sectional view of pcb assembly highlighting all laser mouse components (laser mouse sensor, clip, lens, vcsel, pcb, and base plate) the CC2500 is a single chip 2.4ghz transceiver designed for very low power wireless applications. the circuit is intended for the ism and srd frequency band at 2400mhz-2483.5mhz. the rf transceiver is integrated with a highly confgurable baseband modem which has a confgurable data rate up to 500kbps. CC2500 provides extensive hardware support for packet han - dling, data bufering, burst transmissions, clear channel assessment, link quality indication and wake on radio. the main operating parameters and the 64-byte trans - mit/receive fifos of CC2500 can be controlled via an spi interface. the holtek ht82k68e is an 8-bit high performance peripheral interface otp microcontroller, designed for multiple i/o product and ht68k96e are the 8-bit high performance risc-like microcontroller designed for usb product applications. a halt feature is included in both ht82k68e and ht68k96e to reduce power consump - tion. this kit is connectable to a pc via the usb port. it is based on the 2.4 ghz rf technology, the data gener - ated from displacement detection/button status in the laser mouse is encoded with a pre-defned serial type protocol handled by frmware in the mcu. in the rf stage, the encoded data is used for fsk modulation. the captured data from the rf receiver stage is decoded with a corresponding packet format used for mouse ap - plications. the fnal data is sent to the host through the usb interface. senso r vscel pcb base plate lens surface vscel clip pcb
