SN75185DW Frequently Asked Questions (FAQs)

  • The maximum cable length depends on the data rate and cable characteristics. As a general guideline, for a data rate of 100 Mbps, the maximum cable length is around 100 meters. However, it's recommended to consult the IEEE 802.3 standard for specific guidelines on cable length and transmission distance.
  • Yes, the SN75185DW can be used in a half-duplex mode. The device has a built-in half-duplex mode that allows it to transmit and receive data on the same twisted pair. However, the device must be configured accordingly using the mode pins (MD0 and MD1).
  • To ensure EMC with the SN75185DW, it's recommended to follow proper PCB layout and design guidelines, such as keeping the transmitter and receiver circuits separate, using shielded cables, and providing adequate grounding and decoupling. Additionally, the device should be placed in a metal enclosure to reduce electromagnetic radiation.
  • The power consumption of the SN75185DW depends on the operating mode and data rate. Typically, the device consumes around 200-300 mW of power when operating at 100 Mbps. However, the exact power consumption can be calculated using the device's power consumption formula provided in the datasheet.
  • Yes, the SN75185DW can be used in a redundant or fault-tolerant system. The device has built-in features such as automatic polarity correction and fault detection, which can be used to implement redundant or fault-tolerant systems. Additionally, the device's output can be connected to multiple receivers to provide redundancy.
