The maximum cable length supported by the TSB41LV03APFP is dependent on the specific IEEE 1394 application and the quality of the cable. However, as a general guideline, the IEEE 1394 standard recommends a maximum cable length of 4.5 meters for S400 and S800 modes.
The TSB41LV03APFP provides a VBUS_DETECT pin that can be used to detect the presence of a device on the bus. You can use this pin in conjunction with a voltage comparator and a debouncing circuit to implement a robust hot-plug detection mechanism.
The recommended termination scheme for the TSB41LV03APFP is to use a 1394-compliant termination network, which includes a 1.5-kΩ resistor in series with a 0.01-μF capacitor to ground on each of the twisted pairs.
To ensure EMC compliance, it is recommended to follow proper PCB layout and design guidelines, use shielding and grounding techniques, and implement EMI filtering on the power and signal lines. Additionally, the TSB41LV03APFP has built-in EMI filtering and shielding, which can help reduce electromagnetic emissions.
The power consumption of the TSB41LV03APFP in low-power mode is typically around 100 μA, making it suitable for battery-powered applications.
