General Description
The RTL8214C integrates quad independent 10/100/1000M Ethernet transceivers into a single IC, and performs all
the physical layer (PHY) functions for 1000Base-T, 100Base-TX, and 10Base-T Ethernet on category 5 UTP cable
except 1000Base-T half-duplex. 10Base-T functionality can also be achieved on standard category 3 or 4 cable.
Each of the four independent transceivers features an innovative QSGMII for reduced PCB traces. All transceivers
can communicate with the MAC simultaneously through the QSGMII interface.

Features
Quad-port integrated 10/100/1000Base-T Gigabit Ethernet transceiver
Each port supports full duplex in 10/100/1000M mode (half duplex is only supported in 10/100M mode)
Supports RSGMII-Plus (5Gbps serial high speed interface) in 10/100/1000 mode
Supports QSGMII (5Gbps serial high speed interface) in 10/100/1000 mode
Physical interface supports 1000Base-X
Physical interface supports 100Base-FX
Supports IEEE 802.3az Energy Efficient Ethernet (EEE)
Supports crossover detection and auto correction in 10Base-T/100Base-T

Applications
QSGMII Phyceiver for 1000Base-T/1000Base-X/100Base-FX
