The maximum cable length supported by the SN75C3221DBR is dependent on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths of up to 100 meters at a data rate of 100 Mbps.
The SN75C3221DBR can be configured for half-duplex or full-duplex operation by setting the HDX pin high or low, respectively. When HDX is high, the device operates in half-duplex mode, and when HDX is low, the device operates in full-duplex mode.
The power consumption of the SN75C3221DBR depends on the operating mode and the data rate. In typical operating conditions, the device consumes around 150 mA at 3.3V supply voltage. However, this value can vary depending on the specific application and operating conditions.
The SN75C3221DBR provides a built-in link integrity test (LIT) feature that can be enabled by setting the LIT pin high. When LIT is enabled, the device continuously transmits a test pattern on the transmit pins, allowing the receiver to detect any errors or faults in the link.
The SN75C3221DBR has an operating temperature range of -40°C to 85°C. However, the device can be operated at temperatures above 85°C with reduced performance and reliability.
