Microchip | KSZ9021RLI

The KSZ9021RLI is a 3.46 V, 10/100/1000 Mbps Gigabit Ethernet Transceiver with RGMII Support and its available in LQFP-64 package .

The KSZ9021RL is a completely integrated triple speed Ethernet Physical Layer Transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable .

The KSZ9021RL 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.

Product Features:

• Single-chip 10/100/1000 Mbps IEEE 802.3 compliant Ethernet Transceiver
• RGMII interface compliant to RGMII Version 1.3
• RGMII I/Os with 3.3 V/2.5 V tolerant and programmable timings to adjust and correct delays on both Tx and Rx paths
• Auto-negotiation to automatically select the highest link up speed (10/100/100 Mbps) and duplex (half/full)
• On-chip termination resistors for the differential pairs
• On-chip LDO controller to support single 3.3 V supply
• operation – requires only external FET to generate 1.2 V for the core
• Jumbo frame support up to 16 KB
• 125 MHz Reference Clock Output
• Programmable LED outputs for link, activity and speed
• Baseline Wander Correction
• LinkMD® TDR-based cable diagnostics for identification of faulty copper cabling
• Parametric NAND Tree support for fault detection between chip I/Os and board.
• Loopback modes for diagnostics
