IDT77V106L25

3.3V ATM PHY for 25.6 and 51.2 Mbps IDT77V106L25 FEATURES: Performs the PHY-Transmission Convergence (TC) and DESCRIPTION: The IDT77V106L25 is a member of IDT’s family of products supporting Asynchronous Transfer Mode (ATM) data communications and networking. The IDT77V106L25 implements the physical layer for 25.6 Mbps ATM, connecting a serial copper link (UTP Category 3 and 5) to an ATM layer device such as a SAR or a switch ASIC. The IDT77V106L25 also operates at 51.2 Mbps and is well suited to back-plane driving applications. The 77V106L25 utilizes an 8-bit UTOPIA interface on the cell side. The IDT77V106L25 is fabricated using IDT’s state-of-the-art CMOS technology, providing the highest levels of integration, performance and reliability, with the low-power consumption characteristics of CMOS. Physical Media Dependent (PMD) Sublayer functions of the Physical Layer Compliant to ATM Forum (af-phy-040.000) and ITU-T I.432.5 specifications for 25.6Mbps physical interface Also operates at 51.2Mbps data rate 8-bit UTOPIA Level 1 Interface 3-Cell Transmit & Receive FIFOs Receiver Auto-Synchronization and Good Signal Indication LED Interface for status signalling Supports UTP Category 3 and 5 physical media Interfaces to standard magnetics Low-Power CMOS 3.3V supply with 5V tolerant inputs 64-lead TQFP Package (10 x 10 mm) Commercial and Industrial Temperature Ranges APPLICATIONS: Up to 51.2Mbps backplane transmission Rack-to-rack short links ...
