產品介紹

支援GMII/ MII的乙太網路收發器
* Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet transceiver
* GMII/MII standard interface with 3.3V/2.5V/1.8V tolerant I/Os
* Auto-negotiation to automatically select the highest linkup speed (10/100/1000Mbps) 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 one external FET to generate 1.2V for the core
* Jumbo frame support up to 16KB
* 125MHz Reference Clock Output
* Energy-detect power-down mode for reduced power consumption when the cable is not attached
* Energy Efficient Ethernet (EEE) support with low-power idle (LPI) mode and clock stoppage for 100Base-TX/1000Base-T and transmit amplitude reduction with 10Base-Te option
* Wake-on-LAN (WOL) support with robust custom-packet detection
* Programmable LED outputs for link, activity, and speed
* Baseline wander correction
* LinkMD® TDR-based cable diagnostic to identify faulty copper cabling
* Parametric NAND tree support to detect faults between chip I/Os and board
* Loopback modes for diagnostics
* Automatic MDI/MDI-X crossover to detect and correct pair swap at all speeds of operation
* Automatic detection and correction of pair swaps, pair skew, and pair polarity
* MDC/MDIO management interface for PHY register configuration
* Interrupt pin option
* Power-down and power-saving modes
* Operating voltages:
   - Core (DVDDL, AVDDL, AVDDL_PLL): 1.2V (external FET or regulator)
   - VDD I/O (DVDDH): 3.3V, 2.5V, or 1.8V
   - Transceiver (AVDDH): 3.3V or 2.5V (commercial temp)
* Available in a 64-pin QFN (8mm x 8mm) package
