2. Block Diagram and Operation
QUADRATURE OUTPUT
Figure 3. Block Diagram In the traditional optical mouse, it uses LED as a light source. The light illuminates on the working surface and generates the bright and dark shadow that shows the micro-texture of the surface. The imaging sensor in the optical mouse chip captures sequential this micro-texture images of the working surface. Based on the captured images, the optical chip can determine the speed and direction when the optical mouse is moving. Thus, for the more rough surface, the more obvious shadow image will be generated and much easier to determine the movement and direction. The PAW3603DH is a CMOS laser mouse sensor with DSP integration chip that serves as a non-mechanical motion estimation engine for implementing a computer mouse. It is based on new laser speckle navigation technology. In the laser mouse, it uses laser diode (LD), specially uses VCSEL (Vertical Cavity Surface Emitting Laser) as light source, where laser is one kind of coherent light. When this light illuminates on the working surface, the surface will reflect and diffuse the incident light and generates speckle pattern. The imaging sensor in the laser mouse chip detects the speckle pattern that generated from the working surface and determines the movement and direction. Since the speckle pattern can be generated on the most of the surface if this surface is not perfect smooth or transparent, the laser mouse can adapt on more surfaces as compared with traditional LED-based optical mouse. The sensor is in a 20-pin optical package. The output format is twochannel 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. The word "mouse sensor," instead of PAW3603DH, is used in the document.

CMOS Laser Mouse Sensor
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 mouse sensor tells the 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. The following diagrams show the timing for positive X motion, to the right or positive Y motion, up.

7. Serial Interface
The synchronous serial port is used to set and read parameters in the mouse sensor, 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 mouse controller. SDIO: The serial data line is used to write and read data. PD: third line is sometimes involved. PD line (Power Down pin) is usually used to place the mouse sensor in a low power mode to meet USB suspend specification. PD line can also be used to force resynchronization between the mouse controller and the mouse sensor in case of an error.
7.1 Transmission Protocol
The transmission protocol is a two-wire link, half duplex protocol between the mouse controller and the mouse sensor. All data changes on SDIO are initiated by the falling edge on SCLK. The mouse controller always initiates communication; the mouse sensor 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 bit 7 as its MSB to indicate data direction. The second byte contains the data.

7.1.1 Write Operation
A write operation, which means that data is going from the mouse controller to the mouse sensor, is always initiated by the mouse 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 mouse controller changes SDIO on falling edges of SCLK. The mouse sensor reads SDIO on rising edges of SCLK.

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

7.2 Re-Synchronous Serial Interface
If the mouse controller and the mouse sensor get out of synchronization, then the data either written or read from the registers will be incorrect. In such a case, an easy way to solve this condition is to toggle the SCLK line from high to low to high and wait at least tSIWTT to reach re-synchronous the parts after an incorrect read. This method is called by “watchdog timer timeout”. The mouse sensor will reset the serial port but will not reset the registers and be prepared for the beginning of a new transmission.

Power On Problem - The problem occurs if the mouse sensor powers up before the mouse controller sets the SCLK and SDIO lines to be output. The mouse sensor and the mouse controller might get out of synchronization due to power on problem. An easy way to solve this is to use “watchdog timer timeout”. ESD Events - The mouse sensor and the mouse controller might get out of synchronization due to ESD events. An easy way to solve this is to use “watchdog timer timeout”
7.3 Collision Detection on SDIO
The only time that the mouse sensor drives the SDIO line is during a READ operation. To avoid data collisions, the mouse controller should release SDIO before the falling edge of SCLK after the last address bit. The mouse sensor begins to drive SDIO after the next falling edge of SCLK. The mouse sensor releases SDIO of the rising SCLK edge after the last data bit. The mouse 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 mouse controller should not leave SDIO floating until the next transmission (although that will not cause any communication difficulties).
7.4 Power Down Mode
There are two different ways to entry power down mode, using the PD line (see Section 7.4.1) or register setting (see Section 7.4.2).
7.4.1 PD Line Power Down Mode
To place the mouse sensor in a low power mode to meet USB suspend specification raises the PD line at least tPDW. Then PD line can stay high, with the mouse sensor in the shutdown state, or the PD pin can be lowered, returning the mouse sensor to normal operation.

7.4.2 Register Power Down Mode
The mouse sensor can be placed in a power down mode by setting PD_enh bit in the configuration register via a serial port write operation. After setting the configuration register, wait at least 1frame times. To get the chip out of the power down mode, clear PD_enh bit in the configuration register via a serial port write operation. In the power down mode, the serial interface watchdog timer is not available (see Section 7.2). But, the serial interface still can read/write normally. For an accurate report after leave the power down mode, wait about 3ms before the mouse controller is able to issue any write/read operation to the mouse sensor.

7.5 Error Detection
1. The mouse 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 mouse controller can verify the synchronization of the serial port by periodically reading the product ID register.
8. SWKINT Timing
When the mouse sensor is in sleep mode and the mouse controller is also in sleep mode, if the mouse sensor finds motion occurred at this moment, the mouse sensor wake mouse controller up promptly via SWKINT.

9.4 PCB Layout Consideration
1. Caps for pins 5, 8, 9, 10 must have trace lengths less than 5mm. 2. The trace lengths of OSCOUT, OSCIN must less than 6mm. 3. Avoid the eye safety issue, please placement the R1_1 ~ R1_5 and VR1 in a straight line and avoid any resistor to short each other or short to VCC. 4. Avoid the eye safety issue, please guard the trace from LD’s cathode to mouse sensor’s PIN2 (LD) and avoid short to ground.
