1 / 138 page  ICS1893BF, Rev. E, 8/11/09 August, 2009 IDT reserves the right to make changes in the device data identified in this publication without further notice. IDT advises its customers to obtain the latest version of all device data to verify that any information being relied upon by the customer is current and accurate. Integrated Device Technology, Inc. 3.3-V 10Base-T/100Base-TX Integrated PHYceiver ™ ICS1893BF Document Type: Data Sheet Document Stage: Rev. E Release Features • 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. • 10Base-T and 100Base-TX IEEE 8802.3 compliant • Single 3.3V power supply • Highly configurable, supports: – Media Independent Interface (MII) – Auto-Negotiation with Parallel detection – Node applications, managed or unmanaged – 10M or 100M full and half-duplex modes – Loopback mode for Diagnostic Functions – Auto-MDI/MDIX crossover correction • Low-power CMOS (typically 400 mW) • Power-Down mode typically 21mW • Clock and crystal supported • Fully integrated, DSP-based PMD includes: – Adaptive equalization and baseline-wander correction – Transmit wave shaping and stream cipher scrambler – MLT-3 encoder and NRZ/NRZI encoder • Small footprint 48-pin 300 mil. SSOP package • Also available in small footprint 56-pin 8x8 MLF2 package • Available in Industrial Temp and Lead Free NOTE: EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 General The ICS1893BF 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 ICS1893BF is intended for MII, Node applications that require the Auto-MDIX feature that automatically corrects crossover errors in plant wiring. The ICS1893BF 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 100MHz. With this ICS-patented technology, the ICS1893BF can virtually eliminate errors from killer packets. The ICS1893BF provides a Serial-Management Interface for exchanging command and status information with a Station-Management (STA) entity. The ICS1893BF 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 ICS1893BF is available in a 300-mil 48-lead SSOP package. The ICS1893BF shares the same proven performance circuitry with the ICS1893AF but is not a pin-for-pin replacement of the 1893AF. An application note for a dual footprint layout to accommodate ICS1893AF or ICS1893BF is available on the ICS website. Applications: NIC cards, PC motherboards, switches, routers, DSL and cable modems, game machines, printers.
