Texas Instruments provides a recommended PCB layout in the application note SLVA704, which includes guidelines for trace routing, component placement, and decoupling to minimize EMI and ensure signal integrity.
The termination resistors for the SN65LBC171DWR depend on the specific application and transmission line impedance. TI recommends using the TDR (Time Domain Reflectometry) method to determine the optimal termination resistors. A detailed explanation can be found in the application note SLVA705.
The maximum cable length supported by the SN65LBC171DWR depends on the specific application, cable type, and signal frequency. As a general guideline, TI recommends limiting the cable length to 10 meters for LVDS signals up to 1.5 Gbps. For longer cable lengths, repeaters or active cables may be necessary.
To handle hot swapping with the SN65LBC171DWR, TI recommends using a hot-swap controller, such as the TPS2115A, to control the power sequencing and voltage ramp-up. Additionally, ensure that the device is powered down before disconnecting the cable to prevent damage.
TI recommends powering up the VCC supply before the VCCA supply, and powering down the VCCA supply before the VCC supply. This ensures that the internal voltage regulators are properly sequenced to prevent damage or malfunction.
