Part Number: TIDA-01487 Hello, I would like to isolate CAN running 5 Mbps . However I am not able to do that. I used faster Logic-Gates (74ACT line), faster CAN transceiver (up to 8Mbps), and lowered the delay of the delay line to 100ns. Everything works…
Part Number: TIDA-01487 Other Parts Discussed in Thread: SN65HVD23 I saw the previous post about inserting a microcontroller into the TIDA-01487 to make a bridge. I want to make sure I understand Eric Schott's suggestion. Would this diagram be the…
Part Number: TIDA-01487 Hi TI,
I am trying to understand the design about TIDA-01487
Have some questions :
1. What is the relationship between delay time 210ns and "higher CAN data rates as 2Mbps" .
If my data rates only 1Mbps, best delay time…
Part Number: TIDA-01487 Other Parts Discussed in Thread: TINA-TI An earlier thread referenced the TINA model files of the TIDA-01487 reference design ("Isolated CAN Flexible Data (FD) Rate Repeater"). However, I don't see this file availabl…
Part Number: TIDA-01487 Other Parts Discussed in Thread: TINA-TI Hi,
in order to create a CAN bus with several stubs we used the AMIS 42700.
As this chip is obsolete we used the arbitration circuit from TIDA-01487 to replace the IC.
The problem with…
Part Number: TIDA-01487 Dear sir,
we wish to fabricate 3 boards as is, for our further testing. But our PCB engineer reviewed the "GERBER FILE - TIDA-01487" in the design file tab, and noticed that the plane layers of GND and VDD are missing.…
Part Number: TIDA-01487 Hi TI,
I am trying to understand the statement in section 2.4.3 of TI Designs: TIDA-01487 Isolated CAN FD Repeater Reference Design.
"The asymmetric delay of 210 ns is needed to support higher CAN data rates as 2Mbps." …
Part Number: TIDA-01487 Hi, in my application i use 1 TIDA-01487 circuit to insulate 1 node of bus. the bus has 4 node and works fine. I can monitor the bus with CANKing and the error counter is zero.
If i use 2 TIDA-01487 to isolate a second node i get…
Part Number: TIDA-01487 Other Parts Discussed in Thread: TINA-TI , SN7404 , SN74HC08 , SN74HC32 , Tool/software: TINA-TI or Spice Models In TIDA-01487 schematic, the SN74LVC2G132DCTR, SN74LVC2G07DBVR, SN74LVC2G04DBVR, SN74LVC2G08DCUR and SN74LV32APWR are used…
Part Number: TIDA-01487 I've been working with this reference design myself, at first with my own board, but more recently with the exact board files that TI gives in their reference design page. I've found that I can run the CAN just fine at 800 khz…
