Part Number: ISO1042-Q1 Other Parts Discussed in Thread: ISO1042 , Tool/software: Hello team,
Good day!
How to test and verify the CAN waveforms quality and signal integrity?
Can you share the test method/setup/conditions and follow which standard? It…
Part Number: ISO1042 Hello TI,
I am using ISO1042 CAN transceiver to communicate with other controller with my controller. In the datasheet it was recommended to use 4.7uF bulk capacitor at Vcc2. Could you please suggest whats the size of the capacitor…
Part Number: ISO1042 Tool/software: I am using ISO1042QDWRQ1 for CAN communication. I have been using a series current limiter resistor of 100E/0.75W on the output CAN_H and CAN_L. I also have used split termination for 120E impedance (2 x 60.4 ohm)…
Part Number: ISO1042-Q1 Tool/software: To check the communication success rates of data rates and the length of the CAN bus wires, I had a test.
Connect a resistor(To create resistance by the length of the bus wires) between the master board and the…
Hello Vishal,
Good question. The propagation delay will be heavily affected by bus capacitance. The spec is tested under specific load conditions for this reason. The load conditions are an RL = 60ohm and a CL = 100pF. Changing data rate should note affect…
Part Number: ISO1042-Q1 Hello team,
Could you pls. help clarify the Leakage current value of ISO1042BQDWVRQ1 when test it under surge/impulse voltage ?
We do not find relevant info. in its datasheet.
Thanks.
Part Number: ISO1042-Q1 The operating voltage range for primary side is specified from 1.7V to 5.5V (ABS 6V), does the Vin on signal inputs are 5V tolerated when Vcc1 set to 3.3V or 2.5V?
Best Regards,
Robert
Hello Latha,
Based on the information provided so far, we have two concerns with the schematic:
GND_FIL and GND_ISO are connected through a CMC in the schematic. The purpose of the isolator is to prevent the common-mode CANBUS noise from transmitting…
Part Number: ISO1042 Hi,
A follow up on the thread that discussed the max CAN bitrate versus the Recessive bit RC decay:
We are considering a protective network at each CAN node consisting av a simple bidirectional TVS from both CAN_H and CAN_L to the…
Part Number: ISO1042 Hi,
I'm trying to calculate the theoretical max CAN bus speed and have used the recessive RC decay time "method". However, as I understand it the max bitrate with respect to the RC decay time might not be the final limiting factor…
