SN75LVDS389DBTR datasheet by Texas Instruments

SN75LVDS389DBTR Frequently Asked Questions (FAQs)

• What is the maximum cable length supported by the SN75LVDS389DBTR?
  The maximum cable length supported by the SN75LVDS389DBTR depends on the specific application and the type of cable used. However, as a general guideline, Texas Instruments recommends a maximum cable length of 10 meters for a single-ended signal and 20 meters for a differential signal.
• How do I ensure signal integrity with the SN75LVDS389DBTR?
  To ensure signal integrity with the SN75LVDS389DBTR, it is recommended to follow proper PCB design and layout guidelines, such as using differential pairs, minimizing trace length and impedance mismatch, and using termination resistors. Additionally, the use of a common-mode filter or a shielded cable can help to reduce electromagnetic interference (EMI).
• Can the SN75LVDS389DBTR be used in a multi-point bus configuration?
  Yes, the SN75LVDS389DBTR can be used in a multi-point bus configuration. However, it is recommended to use a repeater or a buffer to ensure signal integrity and to prevent signal degradation due to the loading effect of multiple receivers.
• What is the power consumption of the SN75LVDS389DBTR?
  The power consumption of the SN75LVDS389DBTR depends on the specific application and the operating conditions. However, according to the datasheet, the typical power consumption is around 150 mW per channel at a supply voltage of 3.3 V and a data rate of 1.5 Gbps.
• Is the SN75LVDS389DBTR compatible with other LVDS transceivers?
  Yes, the SN75LVDS389DBTR is compatible with other LVDS transceivers that comply with the TIA/EIA-644-A standard. However, it is recommended to verify the compatibility of the specific transceivers and the operating conditions to ensure proper operation.
