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.
The SN65LVDS33DG4 requires a 100-ohm differential termination at the receiver end. A 100-ohm resistor can be used to terminate the LVDS lines. It's also recommended to add a 50-ohm series resistor at the transmitter end to match the impedance of the transmission line.
The power consumption of the SN65LVDS33DG4 depends on the operating frequency and the supply voltage. According to the datasheet, the typical power consumption is around 15 mA at a supply voltage of 3.3 V and an operating frequency of 100 MHz. However, it's recommended to consult the datasheet for more detailed information on power consumption and to perform power calculations based on the specific application.
No, the SN65LVDS33DG4 is designed to operate with a supply voltage of 3.3 V or 2.5 V. Using a 5-V supply voltage may damage the device or affect its performance. It's recommended to use a voltage regulator or a voltage translator to step down the supply voltage to the recommended range.
To ensure signal integrity with the SN65LVDS33DG4, it's recommended to follow proper PCB design practices, such as using a solid ground plane, minimizing signal trace lengths, and using a consistent impedance throughout the transmission line. Additionally, it's recommended to use a signal integrity analysis tool to simulate the signal transmission and identify potential issues.
