Abstract:
1. An integrated system on a chip with LINBUS network communication capabilities, comprising: processing circuitry for performing predefined digital processing functions on the chip; an on-chip free running clock circuit for generating a temperature compensated clock, which said on-chip free running clock circuit does not require a synch signal from external to the chip; a first network communications interface for providing serial communication with an off-chip communications device; a LINBUS network communication interface for digitally communicating with an off-chip LINBUS device for transmitting data thereto and receiving data therefrom, which off-chip LINBUS device has an independent time reference, which communication between said on-chip LINBUS network communication interface and said off-chip LINBUS device is effected without clock recovery, said LINBUS network communication interface having a time-base derived from said temperature compensated clock, which time-base is independent of any timing information in the input data received during a receive operation; and wherein said temperature compensated clock provides an on-chip time reference for both said processing circuitry and said LINBUS network communication interface.
