5.5 PCB Layout Consideration
z Caps for pins 8, 10, 11, 12 must have trace lengths less than 5mm.
z The trace lengths of OSCOUT, OSCIN must less than 6mm.
z The trace length of RFosc, RFcarrier must as short as possible.
5.6 Recommended Value for R1

It is not guaranteed that the performance of PAW3203DI with IR LED is as good as PAW3203DI with red LED.
PAW3203DI is designed to a very good match with red LED, and this combination has the best performance.
