KSZ8873MLLI-TR - Microchip

KSZ8873MLLI-TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the KSZ8873MLLI-TR?
  The recommended PCB layout for the KSZ8873MLLI-TR can be found in the Microchip application note AN-1041, which provides guidelines for PCB design, component placement, and routing to ensure optimal performance and signal integrity.
• How do I configure the KSZ8873MLLI-TR for VLAN tagging?
  The KSZ8873MLLI-TR supports VLAN tagging through its VLAN table. To configure VLAN tagging, you need to program the VLAN table using the SPI interface. The VLAN table consists of 16 entries, each containing a VLAN ID, priority, and port membership. You can refer to the datasheet and the Microchip application note AN-1042 for more information on VLAN configuration.
• What is the maximum cable length supported by the KSZ8873MLLI-TR?
  The KSZ8873MLLI-TR supports cable lengths up to 100 meters for 1000BASE-T and 100BASE-TX, and up to 200 meters for 10BASE-T. However, the actual cable length supported may vary depending on the cable quality, noise environment, and other factors.
• How do I implement power management for the KSZ8873MLLI-TR?
  The KSZ8873MLLI-TR has a built-in power management feature that allows you to control the power consumption of the device. You can use the Power Down (PD) pin to put the device in a low-power state. Additionally, you can use the Wake-On-LAN (WOL) feature to wake up the device from a low-power state when a magic packet is received.
• What is the maximum operating temperature range for the KSZ8873MLLI-TR?
  The KSZ8873MLLI-TR has an operating temperature range of -40°C to 85°C. However, the device can be operated at temperatures above 85°C for short periods of time, but this may affect its reliability and lifespan.
