The maximum cable length supported by the SN65LVDS9638 is dependent on the signal frequency, cable quality, and termination. As a general guideline, Texas Instruments recommends a maximum cable length of 10 meters at 1.5 Gbps and 5 meters at 3 Gbps.
To ensure signal integrity with the SN65LVDS9638, it is recommended to use a differential pair for each signal, maintain a consistent impedance of 100 ohms, and use a common-mode termination of 50 ohms to 100 ohms. Additionally, the use of a shielded cable and proper grounding can help reduce electromagnetic interference (EMI).
The power consumption of the SN65LVDS9638 depends on the operating frequency and supply voltage. At a supply voltage of 3.3V and an operating frequency of 1.5 Gbps, the typical power consumption is around 250 mW. At 3 Gbps, the typical power consumption is around 350 mW.
Yes, the SN65LVDS9638 can be used in a multi-point configuration, but it is not recommended as it can lead to signal degradation and reduced reliability. The device is designed for point-to-point applications, and using it in a multi-point configuration may require additional circuitry and signal conditioning.
The recommended layout and routing for the SN65LVDS9638 involves keeping the differential pairs together, using a consistent impedance of 100 ohms, and minimizing vias and stubs. It is also recommended to keep the device away from noise sources and to use a solid ground plane to reduce electromagnetic interference (EMI).
