Low latency 10/100-Mbps PHY with MII interface and enhanced mode

 

Description

The DP83826 offers low and deterministic latency, low power and supports 10BASE-Te, 100BASE-TX Ethernet protocols to meet stringent requirements in real-time industrial Ethernet systems. The device includes hardware bootstraps to achieve fast link-up time, fast link-drop detection modes and dedicated reference CLKOUT to clock synchronize other modules on the systems.

The two configurable modes are BASIC standard Ethernet mode that uses a common Ethernet pinout, and ENHANCED Ethernet mode which supports standard Ethernet mode and multiple industrial Ethernet fieldbus applications with the additional features and hardware bootstraps configuration.

Features

  • Low and deterministic latency
    • TX latency: 40 ns, RX latency: 170 ns
    • Deterministic latency over power cycles < ±2 ns
    • Fixed phase XI to TX_CLK relationship < ±2 ns
  • Robust and small system solution
  • Two selectable pin modes in single device
    • ENHANCED mode for additional features
    • BASIC mode for common Ethernet pinout
  • Low power consumption < 160 mW
  • MAC interfaces: MII, RMII
  • Programmable energy-saving modes
    • Active sleep
    • Deep power down
    • Wake-on-LAN (WoL)
  • Diagnostic tools: cable diagnostics, built-in self-test (BIST), loopback modes
  • Single, 3.3-V power supply
  • I/O voltages: 1.8 V or 3.3 V
  • RMII back-to-back repeater mode
  • DP83826E operating temperature range: –40°C to 105°C
  • DP83826I operating temperature range: –40°C to 85°C
  • IEEE 802.3 compliant: 10BASE-Te, 100BASE-TX
