The maximum cable length supported by the SN65LVDS1DBVR 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.
The differential lines should be terminated with a 100-ohm resistor at the receiving end to minimize reflections and ensure signal integrity. The termination resistor should be placed as close to the receiver as possible.
The power consumption of the SN65LVDS1DBVR depends on the operating frequency and output load. At a typical operating frequency of 65 MHz, the power consumption is approximately 135 mW. However, this value can vary depending on the specific application and operating conditions.
While the SN65LVDS1DBVR is designed for LVDS applications, it can be used for other differential signaling applications with some limitations. However, the device's performance and signal integrity may not be optimal for non-LVDS applications, and additional circuitry or components may be required to ensure reliable operation.
To ensure EMC in an SN65LVDS1DBVR-based design, follow proper PCB layout and design guidelines, use shielding and grounding techniques, and consider adding electromagnetic interference (EMI) filters or common-mode chokes to minimize radiation and susceptibility.
