Enlargement of the receiver section. The top layer is shown in top view. When a (mini)DIL packaged
detector is used, holes are foreseen for the package (a). The PCB has standard a cutout for a coaxial
type detector (b). Two types of coax packages are foreseen. The pinning of these packages is shown in
bottom view. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13
Enlargement of the transmitter section. The top layer is shown in top view. The picture shows the

General setup of power supply decoupling network: From the global domain a pi filter provides the
voltage for the local voltage domains. Capacitor C2 is placed as close as possible to the IC to reduce
parasitic inductance. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20
Voltage selection jumpers shown with selectable voltages. Note that all jumpers should have identical
voltage and that J202 should be selected to VCC-3.3 V . . . . . . . . . . . . . . . . . . . . . . . . 27
