Texas Instruments provides a recommended PCB layout in the application note SLVA466, which includes guidelines for signal routing, power supply decoupling, and thermal management to ensure optimal performance and minimize signal integrity issues.
To ensure reliable operation over the full industrial temperature range (-40°C to 85°C), it is essential to follow proper PCB design and layout guidelines, use a suitable thermal management strategy, and select components with a compatible temperature rating. Additionally, consider using a thermal pad or heat sink to dissipate heat generated by the device.
Operating the DS92LV18TVVX/NOPB at a lower voltage power supply than the recommended 3.3V may affect its performance, including reduced output current capability, increased propagation delay, and potentially reduced reliability. It is recommended to use a power supply voltage within the specified range (3.0V to 3.6V) to ensure optimal performance and reliability.
To troubleshoot issues with signal integrity or data transmission errors, use a combination of tools such as oscilloscopes, logic analyzers, and signal generators to analyze the signal waveforms and identify potential sources of error. Check for signal attenuation, jitter, and skew, and ensure that the transmission line is properly terminated and matched to the characteristic impedance of the channel.
The DS92LV18TVVX/NOPB has built-in ESD protection diodes on all pins, which provide protection against electrostatic discharge events up to ±2 kV human body model (HBM) and ±200 V machine model (MM). Additionally, the device is designed with latch-up prevention measures to prevent damage from overvoltage or overcurrent conditions.
