IDT77105  
PHY (TC-PMD) for 25.6 Mbps  
ATM Networks  
Features List  
Description  
!
Performs the PHY-Transmission Convergence (TC) and  
The IDT77105 is a member of IDT's family of products developed to  
support Asynchronous Transfer Mode (ATM) data communications and  
networking. The IDT77105 provides the Transmission Convergence  
(TC) and (PMD) layers of a 25.6 Mbps ATM PHY suitable for ATM  
networks using Unshielded Twisted Pair (UTP) Category 3 (or better)  
wiring. The UTOPIA interface provides standardized control and  
communications to other components, such as Segmentation and Reas-  
sembly (SAR) controllers and ATM switches.  
Physical Media Dependent (PMD) Sublayer functions for  
25.6 Mpbs ATM Networks

ITU-T I.432 and I.432.5 compliant  
ATM Forum af-phy-0040 compliant  
UTOPIA Level 1 Interface  
The IDT77105 supports a simple interface to magnetics modules.  
2-Cell Transmit & Receive FIFOs  
Supports Multi PHY Connections  
LED Interface for status signalling  
Supports UTP Category 3 (CAT 3) physical media  
Interfaces to standard magnetics  
Low-Power CMOS  
The IDT77105 is fabricated using IDT's state-of-the-art CMOS tech-  
nology, providing the highest levels of integration, performance and reli-  
ability, with the low-power consumption characteristics of CMOS.
