Patent ID: 7460584

Claim:
A network system, comprising: a direct conversion radio transceiver coupled to a digitizer, integrated within a first integrated device; a medium access controller coupled between a baseband processor and digital control circuitry, integrated within a second integrated device; and a digital interface that couples said first integrated device to said second integrated device; wherein said digitizer comprises: a in-phase receive path analog-to-digital converter; a quadrature-phase receive path analog-to-digital converter; a in-phase transmit path digital-to-analog converter; and a quadrature-phase transmit path digital-to-analog converter; wherein said digital interface comprises transceiver-side digital interface circuitry, including: a plurality of latches coupled to said digital-to-analog converters and to said analog-to-digital converters; a bi-directional bus driver coupled between said plurality of latches and a bi-directional bus; and address control and timing circuitry coupled to said latches; and wherein said digital interface further comprises controller-side digital interface circuitry, including: a second bi-directional bus driver coupled to said bi-directional bus; a second plurality of latches coupled between said second bi-directional bus driver and said baseband processor; and second address control and timing circuitry coupled to said second plurality of latches.
