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' (SLMA002) for more detailed information on cable length and signal integrity.
The SN65LVDS20DRFR has internal 100-ohm differential termination resistors, so no external termination resistors are required. However, it's recommended to add a 0.1-uF capacitor between the VCC and GND pins to filter the power supply and reduce noise.
The power consumption of the SN65LVDS20DRFR depends on the operating frequency and the load capacitance. According to the datasheet, the typical power consumption is around 15 mA at a frequency of 100 MHz and a load capacitance of 10 pF. However, it's recommended to consult the datasheet and perform power consumption calculations based on the specific application requirements.
Yes, the SN65LVDS20DRFR is designed for high-speed data transmission applications up to 600 Mbps. It has a low propagation delay of around 1.5 ns and a low jitter of around 100 ps, making it suitable for high-speed data transmission applications such as video transmission, high-speed data acquisition, and more.
To ensure signal integrity in your LVDS design, it's recommended to follow best practices such as using a differential pair for the LVDS signals, keeping the signal traces short and matched, using a ground plane to reduce noise, and adding decoupling capacitors to filter the power supply. Additionally, it's recommended to simulate the signal integrity using tools such as IBIS or SPICE models to ensure that the design meets the signal integrity requirements.
