SASF546-P26-X1 - Lighthorse

SASF546-P26-X1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Lighthorse Technologies recommends a 4-layer PCB with a dedicated ground plane and thermal vias to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad with a minimum size of 10 mm x 10 mm is recommended for heat sinking.
• How do I ensure reliable operation in high-vibration environments?
  To ensure reliable operation in high-vibration environments, Lighthorse Technologies recommends securing the module using a combination of screws and adhesive. The module should be mounted on a rigid PCB with a minimum thickness of 1.6 mm. Additionally, the use of vibration-dampening materials such as silicone or rubber can help reduce the impact of vibrations.
• What is the maximum operating temperature range for this module?
  The SASF546-P26-X1 module is designed to operate within a temperature range of -40°C to +85°C. However, Lighthorse Technologies recommends operating the module within a temperature range of -20°C to +70°C for optimal performance and reliability.
• Can I use this module in a humid or high-moisture environment?
  The SASF546-P26-X1 module is designed to operate in environments with a relative humidity of up to 80%. However, Lighthorse Technologies recommends taking additional precautions such as conformal coating or potting to ensure reliable operation in high-moisture environments.
• What is the recommended power-up sequence for this module?
  Lighthorse Technologies recommends a power-up sequence of VCC followed by VDD. The power-up sequence should be controlled using a soft-start circuit to prevent inrush currents and ensure reliable operation.
