8 / 26 page TH8056 Enhanced Single Wire CAN Transceiver TH8056 – Datasheet Page 8 of 26 3901008056 March 2007 Rev 012 [1] The maximum signal delay time for a bus rising edge is measured from Vcmos il on the TxD input pin to the VihMax + V g off max level on CANH at maximum network time constant , minimum signal delay time for a bus rising edge is measured from Vcmos ih on the TxD input pin to 1V on CANH at minimum network time constant .These definitions are valid in both normal and HVWU mode [2] The maximum signal delay time for a bus rising edge in HVWU mode is measured from Vcmos il on the TxD input pin to the VihWUMax + V g off max level on CANH at maximum network time constant, minimum signal delay time for a bus rising edge is measured from Vcmos ih on the TxD input pin to 1V on CANH at minimum network time constant [3] Maximum signal delay time for a bus falling edge is measured from V cmos ih on the TxD input pin to 1V on CANH at maximum network time constant, minimum signal delay time for a bus falling edge is measured from V cmos ih on the TxD input pin to the VihMax + V g off max level on CANH. These definitions are valid in both normal and HVWU mode. [4] The signal delay time in high-speed mode for a bus rising edge is measured from Vcmos il on the TxD input pin to the VihMax + V g off max level on CANH at maximum high-speed network time constant. [5] The signal delay time in high-speed mode for a bus falling edge is measured from Vcmos ih on the TxD input pin to 1V on CANH at maximum high-speed network time constant [6] Receive delay time is measured from the rising / falling edge crossing of the nominal Vih value on CANH to the falling (Vcmos_il_max) / rising (Vcmos_ih_min) edge of RxD. This parameter is tested by applying a square wave signal to CANH. The minimum slew rate for the bus rising and falling edges is 50V/us. The low level on bus is always 0V. For normal mode and high-speed mode testing the high level on bus is 4V. For HVWU mode testing the high level on bus is Vbat – 2V. 2.5 Bus loading requirements Parameter Symbol Min Typ Max Unit Number of system nodes 2 32 Network distance between any two ECU nodes Bus length 60 M Node Series Inductor Resistance (if required) Rind 3.5 Ohm Ground Offset Voltage Vgoff 1.3 V Ground Offset Voltage, low battery Vgofflb 0.1 VBAT 0.6 V Device Capacitance (unit load) Cul 135 150 300 pF Network Total Capacitance Ctl 396 19000 pF Device Resistance (unit load) Rul 6435 6490 6665 Ohm Device Resistance (min load) Rmin 2000 Ohm Network Total Resistance Rtl 200 3332 Ohm High-Speed Mode Network Resistance to GND Rload 75 135 Ohm Network Time Constant [1] τ 1 4 µs Network Time Constant, high-speed mode [1] τ 1.5 µs [1] The network time constant incorporates the bus wiring capacitance. The minimum value is selected to limit radiated emissions. The maximum value is selected to ensure proper communication under all communication modes. Not all combinations of R and C are possible. The following load conditions are used for the measurement of the dynamic characteristics: Normal and high volt.
