Features

Supports 10/100Mbps dual-rate Ethernet communication

The ICS1893CKILFT supports both 10BASE-T and 100BASE-TX Ethernet standards, enabling data transmission at 10Mbps or 100Mbps depending on network connectivity. This dual-rate support allows it to adapt to network devices of varying performance levels and remains compatible with existing Ethernet infrastructure.

Integrated Ethernet physical layer transceiver function

This device is responsible for signal conversion between the MAC controller and the Ethernet physical transmission medium, providing physical layer encoding, decoding, and data transmission/reception functions. Connecting to the MAC controller via the MII interface reduces the complexity of independent physical layer interface circuits in the system design.

Supports automatic negotiation function

The ICS1893C series supports Ethernet auto-negotiation, which determines the appropriate communication mode and transmission rate based on the capabilities of the connected devices. This feature helps improve connectivity compatibility between different network devices and reduces the need for manual network speed configuration.

MII and MDI interface support

The device provides an MII data interface for connecting to an Ethernet MAC controller, and also connects to external Ethernet physical lines via MDI-related interfaces. This architecture separates the MAC layer and PHY layer functions, facilitating modular design of network controllers and physical layer devices.

Industrial temperature range and compact packaging

The ICS1893CKILFT supports an operating temperature range of –40°C to +85°C, making it suitable for network communication equipment in industrial environments. Its 56-pin MLF2 package, measuring 8mm × 8mm, meets the PCB mounting space requirements of embedded network devices.
