DS3102
Stratum 2/3E/3 Timing Card IC with Synchronous Ethernet Support |
Overview
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. |
