FAQs:
1 What is the KTI226LM S RKTT chip
It is a single port 2.5G Ethernet controller chip from Intel belonging to the commercial standard LM version of the I226 series, integrating both a MAC controller and PHY physical layer.
2 What network speeds does this chip support
It supports auto-negotiation of 10M, 100M, 1G, and 2.5G Ethernet speeds and is fully backward compatible with Gigabit and Fast Ethernet environments.
3 What package and pin count does it use
It adopts a PG-VQFN-56 no-lead surface mount package with 56 pins and a standard footprint of 7 by 7 millimeters, classified as a compact industrial-grade design.
4 What are the supply voltage and operating temperature ranges
It uses a multi-voltage power design. Due to the commercial standard grade suffix, the operating temperature range is typically from 0 degrees Celsius to 70 degrees Celsius.
5 What host bus interface does it support
It supports a single lane PCIe (Gen 2/3) high-speed bus interface for high throughput data exchange with the system host chip or CPU.
6 What advanced network features does this chip support
It supports 9KB Jumbo Frames, VLAN filtering, and hardware checksum offloading acceleration features to improve network efficiency.
