Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-frequency design practices, such as using a solid ground plane, minimizing trace lengths, and avoiding vias under the device. Additionally, ensure that the analog and digital grounds are separated and connected at a single point.
To minimize high-frequency noise and EMI, use a multi-layer PCB with a solid ground plane, and ensure that the device is placed close to the analog signal sources. Use shielding, filtering, and decoupling capacitors as necessary. Also, consider using a common-mode choke or a ferrite bead to filter out high-frequency noise.
The TMUX7348FRTJR is rated for operation from -40°C to 125°C. However, it's essential to consider the thermal design and ensure that the device is properly heat-sunk to maintain a safe operating temperature.
To minimize power consumption, ensure that the device is operated at the lowest possible supply voltage (1.71V) and that the output buffers are disabled when not in use. Additionally, consider using the device's power-down mode or shutdown feature to reduce power consumption during idle periods.
The recommended input termination is a 50Ω resistor to ground, while the recommended output termination is a 50Ω resistor to VCC. However, the specific termination requirements may vary depending on the application and signal frequencies involved.
