Texas Instruments provides a recommended PCB layout in the THS4271DGNR evaluation module (EVM) documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The optimal termination resistors depend on the specific application and signal characteristics. TI provides a termination resistor calculator tool to help designers select the appropriate resistors based on their specific requirements.
The THS4271DGNR is specified to operate from -40°C to 125°C, but it's essential to consider the derating of the device's performance and reliability at extreme temperatures. Consult the datasheet and application notes for more information.
To ensure EMI compliance, follow proper PCB layout and design guidelines, use shielding and filtering techniques, and consider the device's EMI performance characteristics, such as its common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR).
A recommended power supply decoupling scheme includes using a combination of ceramic and electrolytic capacitors, with a 10nF to 100nF ceramic capacitor placed close to the device's power pins and a larger electrolytic capacitor (e.g., 10uF) placed further away.
