Figure1. Block Diagram The PAN3203DI is a 27MHz wireless CMOS optical mouse single chip that serves as a non-mechanical motion estimation engine for implementing a wireless mouse. PAN3203DI supports X, Y, Z three axes, and L, R, M, B4, and B5 five buttons. PAN3203DI is in a 24-pin optical package and comes with the resolution of 800 counts per inch (cpi) and the rate of motion up to 28 inches per second. PAN3203DI embedded mouse controller in it so that no additional controller and its component needed.

4.4 PCB Layout Consideration
1. Caps for pins 8, 10, 11, 12 MUST have trace lengths LESS than 5mm. 2. The trace lengths of OSCOUT, OSCIN must less than 6mm. 3. The trace length of RFosc, RFcarrier must as short as possible.
4.5 Recommended Value for R1 4.5.1 Using Red LED
Radiometric intensity of red LED Bin limits (mW/Sr at 20mA) LED Bin Grade N P Q Suggested R1: Red LED Bin Grade N P Q Suggested R1 (ohm) 12 12 12 Min. 14.7 17.7 21.2 Typ. Max. 17.7 21.2 25.4
Note: Tolerance for each bin will be 15%
4.5.2 Using IR LED
Suggested R1: IR LED Bin Grade TBD Suggested R1 (ohm) 0
It is not guaranteed that the performance of PAN3203DI with IR LED is as good as PAN3203DI with red LED. PAN3203DI is designed to a very good match with red LED, and this combination has the best performance.
