The maximum cable length supported by the SN65LVDS2DBVR 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 SN65LVDS2DBVR requires a 100-ohm differential termination resistor at the receiving end of the differential pair. This termination resistor should be placed as close to the receiver as possible to minimize reflections and ensure signal integrity.
The power consumption of the SN65LVDS2DBVR 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 SN65LVDS2DBVR is designed specifically for LVDS applications, it can be used for other differential signaling applications with some modifications. However, the device's performance and signal integrity may not be optimal for non-LVDS applications, and additional circuitry may be required to ensure signal integrity.
To ensure signal integrity and minimize EMI in your SN65LVDS2DBVR design, follow best practices for PCB layout, such as using differential pairs, minimizing trace lengths, and using shielding and grounding techniques. Additionally, ensure that the device is properly terminated and that the power supply is decoupled to minimize noise and radiation.
