PMW3320DB-TYDU entry-gaming optical navigation sensor general description the pixart imaging PMW3320DB-TYDU is a small form factor entry-gaming optical navigation sensor. it is housed in an 8-pin stagg ered dual in-line package (dip). it is capable of high-speed motion detection up to 80ips and 20g; suitable for both wired and wireless g aming navigation system. the low power management in wireless mode can be customized to suit user preferences. in addition, it has an on-chip oscillator and led driver to minimize external components. PMW3320DB-TYDU sensor along with lm31-lng lens, led clip, and hs dl-4261 ir led forms a complete and compact mouse tracking system. there are no moving parts, which translates to high re liability and less maintenance for the end user. precision optica l alignment is not required, thus facilitating high volume assembly. general description key specification ? small form factor or package - 8-pin dip ? operating voltage: 2.1v ? 3.4v ? high speed motion detection up to 80ips and 20g. ? selectable resolutions up to 3500cpi ? three wire serial port interface ? external interrupt output for motion detection ? internal oscillator ? no clock input needed ? minimal number of passive components ? programmable power modes: o corded gaming mode o cordless gaming mode o office mode ? customizable response time and downshift ? time for rest modes ? configurable led operating mode applications ? wired and wireless optical gaming mice and trackballs ? integrated input devices ? battery-powered input devices supply voltage 2.1-3.4v interface 3-wired spi max clock speed : 1 mhz tracking speed up to 80ips acceleration up to 20g cpi resolution up to 3500cpi with 250 cpi/step frame rate max : 5300 fps (frames per sec) operating current vdd=2.2v run avg : 7.9ma rest1 : 1.4ma rest2 : 0.090ma power down : 15ua *including 16ma led current package 8-pin dip

PMW3320DB-TYDU sensor is designed for mounting on a through-hole pcb. there is an aperture stop and features on the package that align to the lens. the lm31-lng lens provides optics for the imaging of the surface as well as illumination of the surface at the optimum angle. featu res on the lens align it to the sensor, base plate, and clip with the led. the led clip holds the led in relation to the lens. the led mus t be inserted into the clip and the led?s leads formed prior to loading on the pcb. the hsdl-4261 ir led is recommended for illumination. figure 4. recommended pcb mechani cal cutouts and spacing (top view)
