The TSA5060A includes a loop amplifier that requires an
external NPN transistor. Care should be taken in the layout
of the application to ground the emitter of the NPN
transistor as close as possible to the ground of the VCO.

The best way to avoid any I
application (i.e. parasitic coupling between the I
lines and the VCO coil) is to avoid the I
come in the RF part by using an I
only the messages for the PLL to go to the PLL and to
avoid unnecessary repeated sending. Such a gate is
integrated in most of the Philips digital demodulators.
