... Data Sheet Engine Knock Signal Processor The HIP9010 is used to provide a method of detecting premature detonation or “Knock” in automotive engines. A block diagram of this IC is shown in Figure 1. The chip alternately selects one of the two sensors mounted on the engine block. Two programmable bandpass filters process the signal from both sensors, and divides the signal into two channels ...

... Description of the HIP9010 Operation This IC is designed universal digitally controlled, analog interface between engine acoustical sensors or accelerometers and internal combustion engine fuel management systems. Two wideband input amplifiers are provided that allow the use of two sensors that may be of the piezoelectric type that can be mounted in optimum locations on either in-line or V-type engine confi ...

... This multiplexes the switch capacitor filter output, the gain control output and the antialiasing filter output. 4-7 HIP9010 Differential to Single-Ended Converter This signal takes the output of the two integrators (through the test-multiplexer circuit) and provides a signal that is the sum of the two signals ...

... All Test function blocks have their outputs buffered by the differential to single ended converter. Their outputs are available at the INTOUT pin 4 of the chip. In the case of the antialias filter test function, the output is taken directly to the INTOUT pin 4 of the chip. 4-8 HIP9010 “0” A bit “ ...
