Description
The
10/100/1000Base-T Gigabit transceivers, supporting data
transfer over standard CAT-5 unshielded twisted pair
cable. This device offers robust performance and low
power consumption. On-chip integration of termination
resistors and LDO controller, along with built-in diagnostic
features, significantly reduces the cost and the complexity
of Gigabit Ethernet applications. This device is ideal for
enabling Gigabit Ethernet performance in SOHO and SMB
networking applications, such as media converter, GEPON
ONU router, wired/wireless Gigabit SOHO/SMB router,
and VoIP gateway.

... Standard compliance ensures to work with other standard compliant, already deployed devices. Flexible MAC interfaces (GMII/MII for KSZ9021GQ and RGMII for KSZ9021RL) support direct connection to MACs in Ethernet processors and switches at various data rates. On-chip termination (eliminating 8 external resistors) not only simplifies PCB design and reduces system BOM, but also improves overall signal integrity and EMI emission ...
