Description
The KSZ8841P is a single chip Fast Ethernet MAC controller with a 32 bit/33MHz PCI processor interface. The KSZ8841P is fully compliant with the IEEE 802.3u standard. It will also be available in an Industrial Temperature part, the KSZ8841-PMQLI from Q1 2006.
FEATUREs
• Supports 10/100BASE-T/TX/FX
• Supports IEEE 802.3x full-duplex flow control and half-duplex backpressure collision flow control
• Fully compliant to the IEEE 802.3u standard
• Supports burst data transfers
• 8KB internal memory for RX/TX FIFO buffers
• Early TX/RX functions to minimize latency through the device
• Single 25MHz reference clock for both PHY + MAC
Benefits
