Highlights
• Single-chip 10/100/1000Mbps IEEE 802.3 compli-
ant Ethernet Transceiver
• RGMII interface compliant to RGMII Version 1.3
• RGMII I/Os with 3.3V/2.5V tolerant and program-
mable timings to adjust and correct delays on
both Tx and Rx paths
• Auto-negotiation to automatically select the high-
est link up speed (10/100/100Mbps) and duplex
(half/full)
• On-chip termination resistors for the differential
pairs
• On-chip LDO controller to support single 3.3V
supply operation – requires only external FET to
generate 1.2V for the core
• Jumbo frame support up to 16KB
• 125MHz Reference Clock Output
• Programmable LED outputs for link, activity and
speed
• Baseline Wander Correction
• LinkMD® TDR-based cable diagnostics for identi-
fication of faulty copper cabling
• Parametric NAND Tree support for fault detection
between chip I/Os and board.
• Loopback modes for diagnostics
• Automatic MDI/MDI-X crossover for detection and
correction of pair swap at all speeds of operation
• Automatic detection and correction of pair swap,
pair skew and pair polarity
• MDC/MDIO Management Interface for PHY regis-
ter configuration
• Interrupt pin option
• Power down and power saving modes
• Operating Voltages
- Core:
1.2V (external FET or regulator)
- I/O:
3.3V or 2.5V
- Transceiver: 3.3V
• Available packages
