The integrated system on a chip with LINBUS network communication capabilities includes processing circuitry for performing predefined digital processing functionalities on the chip. A free running clock circuit generates a temperature compensated clock that does not require a synch signal from external to the chip. A LINBUS network communications interface digitally communicates with off-chip LINBUS devices. Communication between said on-chip LINBUS communications interface and the off-chip LINBUS devices is affected without clock recovery. The LINBUS network communication interface has a time base derived from the temperature compensated clock which is independent of any timing information in the input data received during a receive operation. The temperature compensated clock further provides an on-chip time reference for both the processing circuitry and the LINBUS network communications interface.
