The maximum cable length supported by the SN65LVDS31D is approximately 10 meters (33 feet) at a data rate of 655 Mbps. However, this can vary depending on the specific application and cable quality.
The SN65LVDS31D requires a 100-ohm differential termination resistor at the receiver end. This can be achieved using a 100-ohm resistor connected between the positive and negative differential lines.
The power consumption of the SN65LVDS31D depends on the operating frequency and supply voltage. At a supply voltage of 3.3V and an operating frequency of 65 MHz, the typical power consumption is around 150 mW.
While the SN65LVDS31D is designed for LVDS applications, it can be used for other differential signaling applications with some modifications. However, it's essential to ensure that the device meets the specific requirements of the application, including signal integrity and electromagnetic compatibility (EMC).
To ensure signal integrity with the SN65LVDS31D, it's essential to follow proper PCB design practices, including using controlled impedance traces, minimizing signal reflections, and using adequate decoupling capacitors. Additionally, ensure that the device is operated within its specified frequency range and signal amplitude.
