KSZ9021GQ

KSZ9021GQ KSZ9021RL Product Brief Single-port 10/100/1000Base-T Gigabit Transceiver Description The KSZ9021GQ and KSZ9021RL are single-port 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. The device is available in two RoHS-compliant package options - 128-pin QFP (KSZ9021GQ, supporting GMII/MII) and 64-pin E-LQFP (KSZ9021RL, supporting RGMI). Industrial grade is also available.

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. Integration of a LDO controller permits a low cost MOSFET to supply the 1.2V core, which reduces board cost and simplifies board layout. Built-in LinkMD diagnostics helps identification of common cabling problems, including those not addressed by IEEE. It simplifies network deployment and reduces network downtime. Auto-MDI/MDIX eliminates the need for cross-over cable, thus reduces installation costs.
