Sunnyvale, Calif.Maxim Integrated Products has developed a timing chip, designated the DS3104, that provides full carrier-class clock synchronization for Synchronous Ethernet (SyncE) and mixed SONET/SDH/SyncE line cards in next-generation telecom systems.
The DS3104 employs the company'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 1-GbE, 10-GbE, and 100-Mbit 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.
