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. 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.
While the SN65LVDS150PW is 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 common-mode voltage range and differential output voltage may not be compatible with all RS-422 or RS-485 systems. It's recommended to consult the datasheet and application notes to ensure compatibility.
Proper termination is critical for LVDS signals. The SN65LVDS150PW requires a 100-ohm differential termination at the receiver end. A 100-ohm resistor should be connected between the positive and negative signal lines, and a 50-ohm to 60-ohm series resistor can be added to the transmitter output to improve signal integrity.
The SN65LVDS150PW has a typical power consumption of 135 mW (3.3 V supply, 100 Mbps data rate). This is relatively low compared to other LVDS transceivers. However, the power consumption can increase depending on the data rate, supply voltage, and other factors. It's essential to consider the power consumption of the SN65LVDS150PW when designing the overall system power budget.
The SN65LVDS150PW is rated for operation up to 85°C (junction temperature). However, it's essential to consider the device's thermal characteristics, such as thermal resistance and power dissipation, when designing for high-temperature applications. Additionally, the device's performance and reliability may be affected at higher temperatures, so it's recommended to consult the datasheet and application notes for more information.
