The DS3105 is a low-cost, feature-rich timing IC for telecom line cards. Typically, the device accepts two reference clocks from dual redundant system timing cards. The DS3105 continually monitors both inputs and performs automatic hitless reference switching if the primary reference fails. The highly programmable DS3105 supports numerous input and output frequencies including frequencies required for SONET/SDH, Synchronous Ethernet (1G, 10G, and 100Mbps), wireless base stations, and CMTS systems. PLL bandwidths from 18Hz to 400Hz are supported, and a wide variety of PLL characteristics and device features can be configured to meet the needs of many different applications.\n\n The DS3105 register set is backward compatible with Semtech's ACS8525 line card timing IC. The DS3105 pinout is similar but not identical to the ACS8525.\n\n Click here for secure documentation\n\n\n\n \n\n
