The KSZ9021GQ is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9021GQ provides the industry standard GMII/MII (Gigabit Media Independent Interface / Media Independent Interface) for direct connection to GMII/MII MACs in Gigabit Ethernet Processors and Switches for data transfer at 1000 Mbps or 10/100 Mbps speed. The KSZ9021GQ reduces bo.

KSZ9021GQ
Gigabit Ethernet Transceiver with GMII / MII Support
General Description
Features
The KSZ9021GQ is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.
The KSZ9021GQ provides the industry standard GMII/MII (Gigabit Media Independent Interface / Media Independent Interface) for direct connection to GMII/MII MACs in Gigabit Ethernet Processors and Switches for data transfer at 1000 Mbps or 10/100 Mbps speed.
The KSZ9021GQ reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating a LDO controller to drive a low cost MOSFET to supply the 1.2V core.
