Abstract:
A communications transceiver, comprising:a jack housing having a back surface, a top surface, two side surfaces, a front face, and a recess in the front face of the housing for receiving a mating plug therein; a signal connector within the recess for establishing inbound and outbound signal paths with a corresponding signal connector of the mating plug; a circuit board mounted within said jack housing parallel to said front face and connected to said connector means, said circuit board comprising an electrically conductive layer defining a first internal electromagnetic interference (EMI) shield, said circuit board being spaced apart from the back surface and extending so as to contact the top surface, the bottom surface, and the side surfaces, thereby forming a sealed cavity between the circuit card and the back surface; at least one first circuit device having analog to digital conversion circuitry and being susceptible to EMI and mounted on a first side of said circuit board facing the recess; and at least one second circuit device having a transformer generating EMI and mounted on said circuit board on a second side thereof opposite the first side and enclosed within the sealed cavity so that said first internal EMI shield extends between said at least one first circuit device and said at least one second circuit device, and said second circuit device is contained within the sealed cavity to prevent emitted EMI from escaping the sealed cavity.
