DS3102 3 Stratum 2/3E/3 Timing Card IC with Synchronous Ethernet Support Data Sheet
●General Description
■The DS3102 is a low-cost,feature-rich timing IC for telecom timing cards. With 8 input clocks, the device directly accepts both line timing from a large number of line cards and external timing from external DS1/E1 BITS transceivers. The DS3102 continually monitors all input clocks and performs automatic hitless reference switching if the primary reference fails. The T0 DPLL complies with the Stratum 2,3E,3,4E and 4 requirements of GR-1244, GR-253, G.812 Types I–IV, G.813 and G.8262.The highly programmable DS3102 support numerous input and output frequencies including rates required for SONET/SDH, Synchronous Ethernet (1G,10G, and 100Mbps), wireless base stations, and CMTS systems.PLL bandwidths from 0.5mHz 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. Two DS3102 devices can be configured in a master/slave arrangement for timing card equipment protection.
■The DS3102 register set is backward compatible with Semtech’s ACS8522 timing card IC. The DS3102 has a different package and pin arrangement than the ACS8522.
