Hello,
We are trying to evaluate a low cost option for data transmission from single remote sensor to single master host MCU via SPI operating at ~500kHz clock over a CAT6 STP cable with signal & clock in different pairs paired with ground. The environement shall be near HVAC duct of fans with only electric motors that might generate any visible E/M noise. If required we can reduce the clock frequency further upto 200kHz, however using differential drivers is not possible due to cost constraints.
We want to understand before beginning these experiments, is TXU0304 a suitable device for driving a single SPI slave to transmit data at or below 500kHz over less than 1m distance?
Can we use existing SN74HCS125 to drive the SPI from master end?
Which one would be more suited given the configurations.
Kindly guide if any other better solution is available for this use case.
