... The components interlock as they are mounted onto defined features on the base plate. The ADNS-3080 sensor is designed for mounting on a through hole PCB, looking down. There is an aperture stop and features on the package that align to the lens. The ADNS-2120 lens provides optics for the imaging of the surface as well as illumination of the surface at Figure 3 ...

... NC pins should not be connected to any traces. Surface mount parts are recommended. Care must be taken when interfacing a 5V microcontroller to the ADNS-3080. Serial port inputs on the sensor should be connected to open- drain outputs from the microcontroller or use an active drive level shifter. NPD and RESET should be connected to 5V microcontroller outputs through a resistor divider or other level shifting technique ...

... Synchronous Serial Port The synchronous serial port is used to set and read pa- rameters in the ADNS-3080, and to read out the motion information. The serial port is also used to load SROM data into the ADNS-3080. The port is a four-wire, serial port. The host micro-con- troller always initiates communication; the ADNS-3080 never initiates data transfers ...

... The 250 ns minimum high state of SCLK is also the minimum MISO data hold time of the ADNS-3080. Since the falling edge of SCLK is actually the start of the next read or write command, the ADNS-3080 will hold the state of data on MISO until the falling edge of SCLK. SCLK ...
Page 17
... The falling edge of SCLK for the first address bit of either the read or write command must be at least 250 ns after the last SCLK rising edge of the last data bit of the previous read operation. In addition, during a read operation SCLK should be delayed after the last address bit to ensure that the ADNS-3080 has time to prepare the requested data. 17 ≥ ...

... Notes on Power-up and the serial port Reset Circuit The ADNS-3080 does not perform an internal power up self-reset. The reset pin must be raised and lowered to reset the chip. This should be done every time power is applied. During power-up there will be a period of time after the power supply is high but before any clocks are available ...
