Version 1.00 |26 May 2017 PMJ9100S1: Media Tracking Chip Product Datasheet General Description The PMJ9100S1 is PixArt Imaging’s high performance Media Tracking Chip (MTC), using low power CMOS chip designed specifically to track print media in printer applications. The MTC offers high repeated accuracy with error rate of +/- 15 um over one inch of media movement with speeds up to 15 inches per second (ips). The MTC integrates IR LED light source and optical chip with built in picture element recognition engine and DSP that provides the host system real-time feedback. Key Features  Single axis tracking chip  Integrated 12 pin module  High accuracy with error rate of +/- 15 um over 1 inch travel distance  High resolution of 17904 cpi  Supports Four-Wire Serial Port Interface (SPI)  External interrupt output for motion detection  Internal Oscillator – no clock input needed

Applications

 Print media applications Key Parameters Parameter Value Supply Voltage (V) VDD: 3.0 – 3.6 VDDIO: 3.0 – 3.6 LED Supply Voltage (V) VLED: 3.0 – 3.6 Raw Data Array 128 Col x 16 Row Interface 4-Wire SPI @ 2 MHz Repeated Accuracy Error (um) +/- 15 Media Lift Height (um) +/- 50 Speed (ips) 15 Acceleration (m/s2) 4 Resolution (cpi) 17904 Z Height (mm) (Distance from Lens Reference Plane to Tracking Surface) Package Type 12 pin module

2.0 Operating Specifications

2.1 Absolute Maximum Ratings

Table 2. Absolute Maximum Ratings

Maximum Ratings are those values beyond which damage to the device may occur.
Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional

operation under absolute maximum-rated conditions is not implied.

Functional operation should be restricted to the Recommended Operating Conditions.

2.2 Recommended Operating Conditions

Table 3. Recommended Operating Conditions along long axis of chip's array. Note: PixArt does not guarantee the performance of the system beyond the recommended operating condition limits.

2.3 DC Characteristics

Table 4. DC Electrical Specifications

All the parameters are tested under operating conditions: VDD = 3.3V, VDDIO = 3.3V, VLED = 3.0V, Internal Clock = 80 MHz,

Internal Slow Clock = 1 kHz, TA = 25°C.

Typical pulse current drawn by VLED is 120 mA.

4.2 Assembly Recommendation

 PMJ9100S1 should be mounted flat and parallel to the media to be tracked, spaced with the gap Z shown in Figure 2. lens flange (termed as Lens Reference Plane) to the tracking surface. be tracked, at either at 0° or 180°, with deviations of less than 0.5°. Refer example shown in Figure 4. Mounting Direction. via corresponding guide holes on the baseplate.  Take note to ensure module misalignments during assembly do not exceed the specifications stated in Table 3 . Recommended Operating Conditions. Figure 4. Mounting Direction
