Busa VR sensor conditioning


I was wondering just out of curiosity what chips the Denso ECU uses for the VR sensors (cam and crank)  conditioning LM1825M ?

There is quite a few resistors and diodes before the signal reaches 177G (LM339?). If I remember correctly RR may have a schematic of the path for kawi.

Ok thanks. So they are using a Quad voltage comparator then.

It uses a comparator set up as a zero crossing detector.
