Specifications

Package PQFP 64 Speed NA Temperature I Voltage 3.3 V


Description

3.3V 10BASE-T/100BASE-TX
The 1893CYI-10LFT is a low-power, physical-layer device (PHY) that supports the ISO/IEC 10Base-T and 100Base-TX Carrier-Sense Multiple Access/Collision Detection (CSMA/CD) Ethernet standards, ISO/IEC 8802-3. The 1893CYI-10LFT is intended for MII, Node applications that require the Auto-MDIX feature that automatically corrects crossover errors in plant wiring.

The 1893CYI-10LFT incorporates Digital-Signal Processing (DSP) control in its Physical-Medium Dependent (PMD) sub layer. As a result, it can transmit and receive data on unshielded twisted-pair (UTP) category 5 cables with attenuation in excess of 24 dB at 100 MHz. With this IDT-patented technology, the ICS1893CF can virtually eliminate errors from killer packets.

The 1893CYI-10LFT provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity.

The 1893CYI-10LFT Media-Dependent Interface (MDI) can be configured to provide either half- or full duplex operation at data rates of 10 Mb/s or 100Mb/s.

The 1893CYI-10LFT shares the same proven performance circuitry with the 1893CYI-10LFT and is a pin-for-pin replacement of the 1893CYI-10LFT.
Applications: NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers, network connected appliances, and industrial equipment.

Supports category 5 cables with attenuation in excess of 24dB at 100 MHz.

Single-chip, fully integrated PHY provides PCS, PMA, PMD, and AUTONEG sub layers functions of IEEE standard.
