Features & Applications
The KSZ9021GN is a completely integrated triple speed (10Base-T/100Base-Tx/1000Bade-T) Gigabit Ethernet Physical Layer Transceiver for transimmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable.
It has an operating temperature ranging between 0 to 70°C and its available in QFN-64 surface mount package.
Features:
- Single-chip 10/100/1000Mbps IEEE 802.3 compliant Ethernet Transceiver
- GMII/MII standard compliant interface
- 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 3.3 V supply operation - requires only external FET to generate 1.2 V for the core
- Jumbo frame support upto 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 cooper 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
Applications:
- Laser/Network Printer
- Network Attached storage(NAS)
- Network Server
- Gigabit LAN on Motherboard (GLOM)
- Brodband Gateway
- Gigabit SOHO/SMB Router
- IPTV
- IP Set-top Box
- Game Console
- Triple-play (data, voice, video) Media Center
- Media Converter
