RTL8212-GR Product Details

General Description 

The RTL8212/RTL8212N/8211N integrate dual/single independent Gigabit Ethernet transceivers into a single IC and perform all the physical layer (PHY) functions for 10Base-T, 100Base-TX, and 1000Base-T Ethernet on category 3 (10Base-T) or category 5 UTP cable (except 1000Base-T half duplex operation). 

The devices include the PCS, PMA, and PMD sub-layers. They perform encoding/decoding, clock/data recovery, digital adaptive equalization, echo cancellers, cross-talk elimination, line driver, as well as all other required support circuit functions. The devices also integrate an internal hybrid that allows the use of inexpensive 1:1 transformer modules. 

Each of the two independent transceivers features an industrial standard MII, GMII, and RGMII (Reduced Gigabit Media Independent Interface). To further reduce PCB trace complexity, the RTL8211N/8212N also provides an innovative 2.5Gbps serial interface – the Reduced Serial Gigabit Media Independent Interface (RSGMII). Both dual transceivers can simultaneously communicate with the MAC through the same RSGMII interface. 

The RTL8212/RTL8212N/8211N adopts mixed mode 0.13µm CMOS technology and analog line driver architecture that offers lower power consumption than DAC architecture. 

Two package types are available; a thermally-enhanced 128-pin DHS-QFP (Drop-in Heat Sink QFP) package, and a 76-pin QFN (Quad Flat No-Lead) package. 

„ Single/Dual integrated 10/100/1000Base-T Gigabit Ethernet transceiver
„ Supports full duplex at 10/100/1000Mbps, and half duplex at 10/100Mbps
„ Supports 2.5V I/O (3.3V input tolerance) GMII and RGMII interfaces in 10/100/1000 mode for RTL8212 (DHS-         QFP-128 Package)
„ Supports RSGMII (2.5Gbps serial high speed interface) in 10/100/1000 mode for RTL8212N and RTL8211N         (QFN- 76 Package)
„ Crossover detection and auto correction at all 3 speeds
„ Automatic detection and correction of wiring pair swaps, pair skew, and pair polarity
„ Supports serial LED mode
„ Line driver architecture with low power dissipation Pave=0.78W/port
„ 3.3V, 1.8V, and 1.2V power supply (2.5V is generated by internal linear regulator for Digital I/O pads)
„ Packages:
  ‹ RTL8212: DHS-QFP-128, 14x20mm, 0.5mm lead pitch package
  ‹ RTL8212N and RTL8211N: QFN-76, 9x9mm, 0.4mm pitch package
„ 0.13µm CMOS process
