A good PCB layout for the DS90C387RVJD/NOPB involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The DS90C387RVJD/NOPB requires a single 3.3V power supply. It's recommended to use a low-dropout linear regulator (LDO) to power the device. The power sequencing requirement is to power up the device with a single power supply, with VCCIO and VCCA being powered up simultaneously.
The DS90C387RVJD/NOPB has a maximum junction temperature of 150°C. To ensure reliable operation, it's recommended to keep the device temperature below 125°C. This can be achieved by using a heat sink, improving air flow, and reducing the power consumption of the device.
To troubleshoot issues with the DS90C387RVJD/NOPB, start by checking the power supply and clock signal integrity. Verify that the device is properly configured and that the input signals are within the recommended specifications. Use oscilloscopes and logic analyzers to debug the issue. If the problem persists, consult the Texas Instruments support resources and documentation.
The DS90C387RVJD/NOPB is a high-speed device that can be susceptible to electromagnetic interference (EMI) and radio-frequency interference (RFI). To minimize EMI and RFI, use shielding, keep the device away from noise sources, and use EMI filters and absorbers. Additionally, follow good PCB design practices, such as using a solid ground plane and minimizing the length of the clock signal traces.
