Features & Applications
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 10/100/1000Mbps IEEE 802.3 compliant Ethernet Transceiver
- RGMII interface compliant to RGMII Version 1.3
- RGMII I/Os with 3.3V/2.5V 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 (10/100/100Mbps) and duplex (half/full)
- On-chip termination resistors for the differential pairs
- On-chip LDO controller to support single 3.3V supply
- operation – requires only external FET to generate 1.2V for the core
- Jumbo frame support up to 16KB
- 125MHz 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
