Texas Instruments provides a recommended PCB layout in the DS90CR215MTD evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management.
The DS90CR215MTD requires a 1.8V to 3.3V power supply. To optimize the power supply design, use a low-dropout regulator (LDO) with a high power supply rejection ratio (PSRR) and a low output voltage noise. Additionally, use decoupling capacitors with a low equivalent series resistance (ESR) to minimize power supply noise.
The maximum cable length supported by the DS90CR215MTD depends on the specific application and the type of cable used. However, as a general guideline, the device can support cable lengths up to 10 meters at a data rate of 1.5 Gbps. For longer cable lengths, repeaters or active cables may be required.
To troubleshoot issues with the DS90CR215MTD, use a logic analyzer or an oscilloscope to monitor the device's output signals. Check for proper power supply voltage, clock signal integrity, and data signal quality. Also, refer to the device's datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
The DS90CR215MTD is specified to operate over a temperature range of -40°C to 85°C. However, for high-temperature environments above 85°C, the device's performance and reliability may be affected. Consult with Texas Instruments or a qualified engineer to determine the suitability of the device for high-temperature applications.
