A good PCB layout for the TAS2521IRGET involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the power supply. TI provides a recommended PCB layout in the datasheet and application notes.
To optimize the TAS2521IRGET for low power consumption, use the lowest possible clock frequency, disable unused features, and adjust the bias current to the minimum required for the application. Additionally, use the device's built-in power-saving features, such as the idle mode.
The recommended clock source for the TAS2521IRGET is a high-quality, low-jitter clock source, such as a crystal oscillator or a high-quality clock generator. Avoid using the internal clock generator, as it may not provide the required clock accuracy and stability.
To ensure EMC with the TAS2521IRGET, follow proper PCB design and layout guidelines, use shielding and filtering, and ensure that the device is properly decoupled from the power supply. Additionally, follow TI's guidelines for EMC compliance.
The maximum operating temperature range for the TAS2521IRGET is -40°C to 85°C. However, the device's performance may degrade at higher temperatures, and it's recommended to operate the device within a temperature range of 0°C to 70°C for optimal performance.
