DSC-6237/5IDT82V3011 T1/E1/OC3 WAN PLL WITH SINGLE REFERENCE INPUT DESCRIPTION The IDT82V3011 is a T1/E1/OC3 WAN PLL with single reference 1244-CORE Stratum 4 Enhanced and Stratum 4, and ETSI ETS 300 input. It contains a Digital Phase-Locked Loop (DPLL), which generates 011. It meets the jitter/wander tolerance, jitter/wander transfer, intrinsic low jitter ST-BUS and 19.44 MHz clock and framing signals that are jitter/wander, frequency accuracy, capture range, phase change slope, phase locked to an 8 kHz, 1.544 MHz, 2.048 MHz or 19.44 MHz input holdover frequency accuracy and MTIE (Maximum Time Interval Error) reference. requirements for these specifications. The IDT82V3011 provides 9 types of clock signals (C1.5o, C3o, C6o, The IDT82V3011 can be used in synchronization and timing control C2o, C4o, C8o, C16o, C19o, C32o) and 7 types of framing signals (F0o, for T1, E1 and OC3 systems, or used as ST-BUS clock and frame pulse F8o, F16o, F19o, F32o, RSP, TSP) for multitrunk T1/E1 and STS3/OC3 source. It also can be used in access switch, access routers, ATM edge links. switches, wireless base station controllers, or IADs (Integrated Access The IDT82V3011 is compliant with AT&T TR62411, Telcordia GR- Devices), PBXs, line cards and SONET/SDH equipments.
