ENGLISH DATASHEETS for Realtek RTL8212
Realtek RTL8212 (network chip)
Release: 1.3 from 2007-08-03

Designed only for Realtek RTL8212-GR RTL8212N-GR RTL8211N-GR
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.
