The maximum cable length supported by the SN65LVDS100DGK is approximately 10 meters (33 feet) at a data rate of 655 Mbps. However, this length can vary depending on the specific application, cable quality, and noise environment.
To ensure signal integrity with the SN65LVDS100DGK, it is recommended to use a differential pair for the LVDS signals, keep the signal traces short and well-matched, and use a common-mode choke or ferrite bead to filter out electromagnetic interference (EMI).
While the SN65LVDS100DGK is designed for LVDS applications, it can be used for other differential signaling applications such as RS-422 or RS-485 with some modifications to the circuit design and component selection.
To ensure proper operation, it is recommended to sequence the power supplies to the SN65LVDS100DGK such that the analog power supply (VCCA) is powered up before the digital power supply (VCCD).
For optimal performance, it is recommended to follow a star topology for the LVDS signals, keep the signal traces short and well-matched, and avoid crossing signal traces over each other or over power planes.
