The maximum cable length supported by the SN75C3221EPW depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 100 meters at a data rate of 100 Mbps.
The SN75C3221EPW can be configured for half-duplex or full-duplex operation by setting the appropriate pins on the device. For half-duplex operation, the TXEN pin should be tied to the RXEN pin, while for full-duplex operation, the TXEN pin should be tied to VCC and the RXEN pin should be tied to GND.
The power consumption of the SN75C3221EPW depends on the operating mode and the data rate. In typical operating conditions, the device consumes around 150 mA at 100 Mbps and 50 mA at 10 Mbps.
Yes, the SN75C3221EPW is rated for operation in the industrial temperature range of -40°C to 85°C, making it suitable for use in industrial applications.
To ensure EMC with the SN75C3221EPW, it is recommended to follow proper PCB design and layout guidelines, use shielding and grounding techniques, and implement EMI filtering and shielding on the device's inputs and outputs.
