Multi-chip module for a multi-mode receiver and method therefor

A multi-chip module (MCM) for a multi-mode receiver comprising:

• an MCM substrate having first and second satellite input ports, first and second terrestrial/cable input ports, and first and second transport stream ports;
• a first demodulator die;
• and
• a second demodulator die,
• wherein each of said first and second demodulator die include:
• a first input port coupled to a respective one of said first and second satellite input ports of said MCM substrate;
• a second input port coupled to a respective one of said first and second terrestrial/cable input ports of said MCM substrate;
• a first transport stream port coupled to said first transport stream port of said MCM substrate;
• a second transport stream port coupled to said second transport stream port of said MCM substrate;
• a demodulator core responsive to an input from a selected one of said first input port and said second input port for providing a first transport stream signal to an output thereof;
• and
• a switching circuit for coupling said output of said demodulator core to a selected one of said first and second transport stream ports while keeping another one of said first and second transport stream ports in a high impedance state.

A method for making a multi-chip module (MCM) for use in a multi-mode receiver comprising:

• providing an MCM substrate having first and second satellite input ports, first and second terrestrial/cable input ports, and first and second transport stream ports;
• attaching a first demodulator die to a top side of said MCM substrate, said first demodulator die having a satellite port coupled to said first satellite input port of said MCM substrate, a terrestrial/cable port coupled to said first terrestrial/cable input port of said MCM substrate, and first and second transport stream ports coupled to said first and second transport stream ports of said MCM substrate;
• and
• attaching a second demodulator die to said first demodulator die, said second demodulator die having a satellite port coupled to said second satellite input port of said MCM substrate, a terrestrial/cable port coupled to said second terrestrial/cable input port of said MCM substrate, and first and second transport stream ports coupled to said first and second transport stream ports of said MCM substrate.
