Timing chip enables 1G, 10G Synchronous Ethernet

Sunnyvale, Calif.—Maxim Integrated Products has developed a telecom timing device that enables 1G and 10G synchronous Ethernet and supports SONET/SDH, PDH, and wireless systems.

According to Maxim, the DS3104 is the industry's first timing IC to provide full carrier-class clock synchronization for new Synchronous Ethernet (SyncE) line cards and mixed SONET/SDH/SyncE line cards. The DS3104 employs Maxim's DSP-based digital PLL (DPLL) technology.

Key DS3104 innovations include two independent DPLLs for bidirectional frequency conversion between Ethernet clock rates and SONET/SDH rates, and complete support for all 1G, 10G, and 100M Ethernet MII clock rates. Applications include line cards and other subsystems in a wide variety of wireline and wireless systems, including ADMs, digital cross-connects, carrier-class switches and routers, wireless base stations, DSLAMs and multiservice access nodes.

Availability: Now.
Datasheet: DS3104.
