Overview of KSZ9021RN
8/8 Transceiver Full Gigabit Ethernet 48-QFN (7x7)
Key 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
- Automatic MDI/MDI-X crossover for detection and correction of pair swap at all speeds of operation
- Automatic detection and correction of pair swap, pair skew and pair polarity
- MDC/MDIO Management Interface for PHY register configuration
- Interrupt pin option
- Power down and power saving modes
- Operating Voltages
- Core: 1.2V (external FET or regulator)
- I/O: 3.3V or 2.5V
- Transceiver: 3.3V
- Available packages
