Description

The IDT77V1264L200 is a member of IDT's family of products supporting Asynchronous Transfer Mode (ATM) data communications and networking. The IDT77V1264L200 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 IDT77V1264L200 also operates at 51.2 Mbps and 204.8 Mbps, and is well suited to backplane driving applications.

The 77V1264L200-ATM layer interface is selectable as either: 16-bit UTOPIA Level 2, 8-bit UTOPIA Level 1 Multi-PHY, or quadruple 4-bit DPI (Data Path Interface).

The IDT77V1264L200 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.
