Appendix B: PCB Layout Suggestion The effects of EMI and power supply noise can poten- tially reduce the sensitivity of the receiver, resulting in  reduced link distance. The PCB layout played an impor- tant role to obtain a good PSRR and EM immunity re- sulting in good electrical performance. Things to note: 1.   The ground plane should be continuous under the  part, but should not extend under the shield trace. 2.   The shield trace is a wide, low inductance trace back  to the system ground. CX1, CX2, CX3, CX4, CX5, CX6  and CX7 are optional supply filter capacitors; they  may be left out if a clean power supply is used. 3.   IR and RC VLED can be connected to either unfil- tered or unregulated power supply. The bypass  capacitors should be connection before the current  limiting resistor R3 and R4 respectively. In a noisy  environment, including capacitor CX2 and CX7 can  enhance supply rejection. CX6 and CX3 that are  generally a ceramic capacitor of low inductance  providing a wide frequency response while CX2 and  CX4 are tantalum capacitor of big volume and fast  frequency response. The use of a tantalum capacitor  is more critical on the VLED line, which carries a high  current. 4.   V  pin can be connected to either unfiltered or  CC unregulated power supply. The Resistor, R1 together  with the capacitors, CX1 and CX2 acts as the low  pass filter. 5.   IOV ...

Window Material Almost any plastic material will work as a window mate- rial.  Polycarbonate  is  recommended. The  surface  finish  of the plastic should be smooth, without any texture. An  IR filter dye may be used in the window to make it look  black to the eye, but the total optical loss of the window  should be 10% or less for best optical performance. Light  loss should be measured at 875 nm. The recommended  plastic materials for use as a cosmetic window are avail- able from General Electric Plastics.
