TS3A5018PW Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TS3A5018PW to minimize EMI and ensure reliable operation?
  A good PCB layout for the TS3A5018PW involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the signal sources. Additionally, using a 4-layer PCB with a dedicated power plane and a dedicated ground plane can help reduce EMI.
• How do I ensure the TS3A5018PW is properly powered and what are the power sequencing requirements?
  The TS3A5018PW requires a single 3.3V power supply. It's recommended to power the device after the analog and digital power supplies are stable. The power sequencing requirements are not critical, but it's recommended to power the device after the analog power supply is stable.
• What is the recommended termination scheme for the TS3A5018PW?
  The recommended termination scheme for the TS3A5018PW is to use a 50Ω resistor in series with the output pins (OUTA and OUTB) and a 50Ω load resistor to ground. This ensures proper signal termination and minimizes signal reflections.
• How do I handle the thermal management of the TS3A5018PW?
  The TS3A5018PW has a thermal pad that must be connected to a thermal plane on the PCB to ensure proper heat dissipation. A thermal via array or a thermal pad connected to a ground plane can be used to dissipate heat. Additionally, ensuring good airflow around the device can help reduce the operating temperature.
• What are the recommended input and output signal levels for the TS3A5018PW?
  The recommended input signal levels for the TS3A5018PW are differential signals with a minimum amplitude of 100mV and a maximum amplitude of 2V. The output signal levels are typically 2Vpp differential, but can be adjusted using the output common-mode voltage (VOCM) pin.
