Can bus rise time
WebFeb 29, 2012 · The CAN bus [CANbus] is a Balanced (differential) 2-wire interface running over either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or Ribbon cable. Each node uses a Male 9-pin D connector. The Bit Encoding used is: Non Return to Zero ( NRZ) encoding (with bit-stuffing) for data communication on a differential two wire bus. WebFigure 1: I 2 C Fast Mode Timing Definition. Rise (t r) and Fall (t f) Times. t r is defined as the amount of time taken by the rising edge to reach 70% amplitude from 30% amplitude for either SDA and SCL, while t f is defined as the amount of time taken by the falling edge to reach 30% amplitude from an amplitude of 70%.
