The IDT77V1254L25 is a member of IDT's family of products supporting Asynchronous Transfer Mode (ATM) data communications and networking. The IDT77V1254L25 implements the physical layer for 25.6 Mbps ATM, connecting four serial copper links (UTP Category 3 and 5) to one ATM layer device such as a SAR or a switch ASIC. The IDT77V1254L25 also operates at 51.2 Mbps, and is well suited to backplane driving applications.
The 77V1254L25-to-ATM layer interface is selectable as one of three options: 16-bit UTOPIA Level 2, 8-bit UTOPIA Level 1 Multi-PHY, or quadruple 4-bit DPI (Data Path Interface).
The IDT77V1254L25 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.
