Functional Overview
The KSZ9021GQ is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T) Ethernet Physical Layer
Transceiver solution for transmission and reception of data over a standard CAT-5 unshielded twisted pair (UTP) cable.
Its on-chip proprietary 1000Base-T transceiver and Manchester/MLT-3 signaling-based 10Base-T/100Base-TX
transceivers are all IEEE 802.3 compliant.
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.
On the copper media interface, the KSZ9021GQ can automatically detect and correct for differential pair misplacements
and polarity reversals, and correct propagation delays and re-sync timing between the four differential pairs, as specified
in the IEEE 802.3 standard for 1000Base-T operation.
The KSZ9021GQ provides the GMII/MII interface for a direct and seamless connection to GMACs in Gigabit Ethernet
Processors and Switches for data transfer at 10/100/1000 Mbps speed.
The following figure shows a high-level block diagram of the KSZ9021GQ.
