Integrated Device Technology, Inc. ICS1893CY-10 General The ICS1893CY-10 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. The ICS1893 C Y-10 supports managed or unmanaged node, repeater, and switch applications. www.DataSheet4U.com The ICS1893CY-10 is intended for MII, Node applications Document Type: Data Sheet Document Stage: Preliminary Release 3.3-V 10Base-T/100Base-TX Integrated PHYceiver™ Features • Supports category 5 cables with attenuation in excess of • 24 dB at 100 MHz 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 Low-power, 0.35-micron CMOS (typically 400 mW) Power-down mode typically 21mW Single 3.3-V power supply. Single-chip, fully integrated PHY provides PCS, PMA, PMD, and AUTONEG sublayers of IEEE standard 10Base-T and 100Base-TX IEEE 802.3 compliant Highly configurable design supports: – Node, repeater, and switch applications – Managed and unmanaged applications – 10M or 100M half- and full-duplex modes – Parallel detection – Auto-negotiation, with Next Page capabilities – Auto-MDI/MDIX crossover correction MAC/Repeater Interface can be configured as: – 10M or 100M Media Independent Interface – 100M Symbol Interface (bypasses the PCS) – 10M 7-wire Serial Interface Clock and crystal supported Small Footprint 64-pin Thin Quad Flat Pack (TQFP) Available in Industrial Temperature and Lead-Free that require the Auto-MIDIX feature that automatically corrects crossover errors in plant wiring. The ICS1893CY-10 incorporates digital signal processing (DSP) in its Physical Medium Dependent (PMD) sublayer. 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 ICS-patented technology, the ICS1893CY-10 can virtually eliminate errors from killer packets. The ICS1893CY-10 provides a Serial Management Interface for exchanging command and status information with a Station Management (STA) entity. The ICS1893CY-10 Media Dependent Interface (MDI) can be configured to provide either half- or full-duplex operation at data rates of 10 MHz or 100 MHz. The MDI configuration can be established manually (with input pins or control register settings) or automatically (using the Auto-Negotiation features). When the ICS1893 C Y-10 Auto-Negotiation sublayer is enabled, it exchanges technology capability data with its remote link partner and automatically selects the highest-performance operating mode they have in common. • • • • • • • • • • ICS1893CY-10 Block Diagram 100Base-T 10/100 MII or Alternate MAC/Repeater Interface Interface MUX PCS • Frame • CRS/COL Detection • Parallel to Serial • 4B/5B PMA • Clock Recovery • Link Monitor • Signal Detection • Error Detection TP_PMD • MLT-3 • Stream Cipher • Adaptive Equalizer • Baseline Wander Correction Integrated Switch 10Base-T MII Extended Register Set Low-Jitter Clock Synthesizer Clock Power TwistedPair Interface to Magnetics Modules and RJ45 Connector MII Serial Management Interface Configuration and Status AutoNegotiation LEDs and PHY Address ICS1893CY-10 Rev 1/07 IDT reserves the right to make changes in the device data identified in this publication without further notice.
