The PAN101B is a low cost CMOS-process optical navigation sensor with DSP integration chip that serves as a non-mechanical motion estimation engine for implementing a computer mouse. It is based on optical navigation technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The sensor is in a 20 pin optical package. The output format is two-channel quadrature (X and Y direction), which emulates encoder phototransistors. The current X and Y information are also available in registers accessed via a serial port.

3. Registers and Operation

Register 0x02 allows the user to determine if motion has occurred since the last time it was read. If so, then the user should read registers 0x03 and 0x04 to get the accumulated motion. It also tells if the motion buffers have overflowed since the last reading. The current resolution is also shown. Reading this register freezes the Delta_X and Delta_Y register values. Read this register before reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion register is read a second time, the data in Delta_X and Delta_Y will be lost.

6. Quadrature Mode
The quadrature state of the PAN101B tells mouse controller which direction the mouse is moving in. The output format is two channels quadrature (X and Y direction), which emulates encoder phototransistors. The DSP generates the x and y relative displacement values that are converted into two channel quadrature signals. PAN101B support 400cpi, 800cpi, two types of resolution. The following diagrams show the timing for positive X motion, to the right or positive Y motion, up.

The following state machine shows the states of the quadrature output pins. The three things to note are that state 0 is entered after a power on reset. While the PD pin is asserted, the state machine is halted. Once PD is de-asserted, the state machine picks up from where it left off.

7. Serial Interface
The synchronous serial port is used to set and read parameters in the PAN101B, and can be used to read out the motion information instead of the quadrature data pins. SCLK: The serial clock line. It is always generated by the host micro-controller. SDIO: The serial data line used for write and read data. PD: A third line is sometimes involved. PD (Power Down pin) is usually used to place the PAN101B in a low power mode to meet USB suspend specification. PD can also be used to force resynchronization between the micro-controller and the PAN101B in case of an error.
7.1 Transmission Protocol
The transmission protocol is a two-wire link, half duplex protocol between the micro-controller and PAN101B. All data changes on SDIO are initiated by the falling edge on SCLK. The host microcontroller always initiates communication; the PAN101B never initiates data transfers. The transmission protocol consists of the two operation modes: - Write Operation. - Read Operation. Both of the two operation modes consist of two bytes. The first byte contains the address (seven bits) and has a bit7 as its MSB to indicate data direction. The second byte contains the data.

Figure 12. Transmission Protocol 7.1.1 Write Operation
A write operation, which means that data is going from the micro-controller to the PAN101B, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address (seven bits) and has a "1" as its MSB to indicate data direction. The second byte contains the data. The transfer is synchronized by SCLK. The micro-controller changes SDIO on falling edges of SCLK. The PAN101B reads SDIO on rising edges of SCLK.

A read operation, which means that data is going from the PAN101B to the micro-controller, is always initiated by the micro-controller and consists of two bytes. The first byte contains the address, is written by the micro-controller, and has a "0" as its MSB to indicate data direction. The second byte contains the data and is driven by the PAN101B. The transfer is synchronized by SCLK. SDIO is changed on falling edges of SCLK and read on every rising edge of SCLK. The micro-controller must go to a high Z state after the last address data bit. The PAN101B will go to the high Z state after the last data bit.

Figure 14. Read Operation 7.2 Re-Synchronous Serial Interface
There are times when the SDIO line from the PAN101B should be in the Hi-Z state. If the microprocessor has completed a write to the PAN101B, the SDIO line is Hi-Z, since the SDIO pin is still configured as an input. However, if the last operation from the microprocessor was a read, the PAN101B will hold the D0 state on SDIO until a rising edge of SCLK. To place the SDIO pin into the Hi-Z state, first raise the PD pin, and then toggle the SCLK line from high to low to high. The SDIO line will now be in the Hi-Z state. The PAN101B and the micro-controller might get out of synchronization due to following condition.
7.2.1 USB suspend
Termination of a transmission by the micro-controller may sometimes be required (for example, due to a USB suspend interrupt during a read operation). To accomplish this the micro-controller should raise PD. The PAN101B will not write to any register and will reset the serial port (but nothing else) and be prepared for the beginning of future transmissions after PD goes low.
7.2.2 Firmware flaws error, or others error
The PAN101B and the micro-controller might get out of synchronization due to micro-controller firmware flaws. The PD pin can stay high, with the PAN101B in the shutdown state, or the PD pin can be lowered, returning the PAN101B to normal operation. If the microprocessor and the PAN101B get out of sync, then the data either written or read from the registers will be incorrect. In such a case, an easy way to solve this is to raise PD to re-sync the parts after an incorrect read. The PAN101B will reset the serial port but will not reset the registers and be prepared for the beginning of a new transmission

7.2.3 Power on problem
The problem occurs if the PAN101B powers up before the microprocessor sets the SCLK and SDIO lines to be output.
7.2.4 ESD events
The PAN101B and the micro-controller might get out of synchronization due to ESD events. If the PAN101B and the micro-controller might get out of synchronization due to power on problem or ESD events. An easy way to solve this is to reset PAN101B.

Figure 15. Power on reset to resync. PAN101B 7.3 Collision detection on SDIO
The only time that the PAN101B drives the SDIO line is during a READ operation. To avoid data collisions, the micro-controller should release SDIO before the falling edge of SCLK after the last address bit. The PAN101B begins to drive SDIO after the next falling edge of SCLK. The PAN101B release SDIO of the rising SCLK edge after the last data bit. The micro-controller can begin driving SDIO any time after that. In order to maintain low power consumption in normal operation or when the PD pin is pulled high, the micro-controller should not leave SDIO floating until the next transmission (although that will not cause any communication difficulties).
7.4 Error detection and recovery
1.The micro-controller can verify success of write operations by issuing a read command to the same address and comparing written data to read data. 2. The micro-controller can verify the synchronization of the serial port by periodically reading the product ID register.

1. Caps for pins 9, 10 MUST have trace lengths LESS than 5mm. 2. The ground wires of pin1(VSS_LED), pin5(VSSD), pin6(VSSA) must be separated from PS2/USB connector ground node in PCB layout. 3. VSS_LED and VSSD must have trace lengths less than 100mm, VSSA must have trace lengths less than 80mm, and typical trace width is 30mil. 4. The trace lengths of OSCOUT, OSCIN must less than 6mm.
