The maximum cable length depends on the specific application and the signal frequency. As a general rule, the maximum cable length for LVDS signals is around 10-15 meters at a frequency of 100 MHz. However, it's recommended to consult the TI application note 'LVDS Owner's Manual' (SLWC073) for more detailed information on cable length and signal integrity.
To ensure signal integrity and minimize EMI, it's essential to follow proper PCB layout and design guidelines. This includes using a solid ground plane, minimizing trace lengths, and using shielding or twisted pairs for the LVDS signals. Additionally, the use of a common-mode choke or a ferrite bead can help to reduce EMI. TI provides a detailed application note 'LVDS Owner's Manual' (SLWC073) that covers these topics in more detail.
The recommended termination scheme for the SN65LVDS1050PW is a 100-ohm differential termination resistor at the receiving end of the LVDS signal. This helps to match the impedance of the transmission line and reduce signal reflections. TI provides more information on termination schemes in the datasheet and application notes.
While the SN65LVDS1050PW is primarily designed for LVDS applications, it can be used for other differential signaling standards like RS-422 or RS-485 with some limitations. However, the device's performance and signal integrity may not be optimal for these applications. It's recommended to consult the datasheet and application notes to determine the feasibility of using the SN65LVDS1050PW for non-LVDS applications.
The SN65LVDS1050PW is not designed to handle hot swapping or hot plugging. It's recommended to ensure that the power supply is stable and the device is properly initialized before connecting or disconnecting the LVDS signals. TI provides guidelines for power sequencing and hot plugging in the datasheet and application notes.
