Other Parts Discussed in Thread: TIDA-060013, P82B715
We are currently working on a condition-monitoring system that involves interfacing multiple I2C and SPI sensors to an MCU in a noisy industrial environment. We have come across the TIDA-060013 reference design, where the designers have successfully connected the B-side of the P82B96 with a CAN transceiver.
We are considering the possibility of replacing the CAN transceiver with LVDS, specifically the DLVDS047, as we are already planning to use the DLVDS047/48 pair for one of our existing SPI lines. Our main concern is whether there are any fundamental issues or potential errors in using the combination of P82B96 and DLVDS047 to achieve better noise immunity in an industrial environment.
Here are the design specifications for our system:
Communication speed: 400kHz
Maximum distance: >5m
Configuration: 1 slave (sensor) to 1 master (MCU)
4 I2C lines, all using the same configuration
P82B96 will be used to convert bidirectional signals into unidirectional signals
We aim to keep the cost of the system as low as possible while prioritizing maximum data integrity in the suggested configuration. Therefore, we kindly request suggestions for cost-optimized options that can ensure reliable data transmission.
Furthermore, we are interested in exploring the feasibility of transmitting the B-side signals over STP cables (24AWG Cat5) without the need for any differential transceivers. We have observed a similar implementation using P82B715 and would appreciate insights on whether this approach is viable for our system.
We sincerely appreciate any insights, advice, or recommendations you can provide.
Thank you in advance.
