MAX306CWI+ datasheet by Maxim Integrated Products

MAX306CWI+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX306CWI+?
  The recommended PCB layout for the MAX306CWI+ involves placing the device near the signal source, using a solid ground plane, and minimizing the length of the signal traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated ground plane and to avoid routing signals under the device.
• How do I ensure the MAX306CWI+ is properly terminated?
  To ensure proper termination, the MAX306CWI+ requires a 50Ω termination resistor to be connected between the output pins (RX+/RX-) and the signal ground. This resistor should be placed as close to the device as possible.
• What is the maximum cable length supported by the MAX306CWI+?
  The MAX306CWI+ supports cable lengths up to 100 meters (328 feet) at data rates up to 100 Mbps. However, the actual cable length supported may vary depending on the specific application and cable characteristics.
• How do I handle ESD protection for the MAX306CWI+?
  The MAX306CWI+ has built-in ESD protection, but additional protection measures can be taken to ensure the device is protected from electrostatic discharge. This includes using ESD-protective packaging, handling the device by the body, and using an ESD wrist strap or mat.
• What is the power consumption of the MAX306CWI+?
  The power consumption of the MAX306CWI+ varies depending on the operating mode and data rate. In normal operation, the device consumes around 150mA at 3.3V. In power-down mode, the current consumption is typically around 10μA.
