Note:
Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device.

Exposure to absolute maximum rating conditions for extended periods may affect reliability.


Description

The IDT82V3001A is a WAN PLL with single reference input. It contains a Digital Phase-Locked Loop (DPLL), which generates ST-BUS clocks and framing signals that are phase locked to a 2.048 MHz, 1.544 MHz or 8 kHz input reference.

The IDT82V3001A provides eight types of clock signals (C1.5o, C3o,C6o, C2o, C4o, C8o, C16o, C32o) and six types of framing signals (F0o,F8o, F16o, F32o, RSP, TSP) for the multitrunk T1 and E1 primary rate transmission links.

The IDT82V3001A is compliant with AT&T TR62411, Telcordia GR-1244-CORE Stratum 4 Enhanced and Stratum 4, ETSI ETS 300 011. Itmeets the jitter/wander tolerance, jitter/wander transfer, intrinsic jitter/ wander, frequency accuracy, capture range, phase change slope, holdover frequency accuracy and MTIE (Maximum Time Interval Error)requirements for these specifications.

The IDT82V3001A can be used in synchronization and timing control for T1 and E1 systems, or used as ST-BUS clock and frame pulse sources. It can also be used in access switch, access routers, ATM edge switches, wireless base station controllers, or IADs (Integrated Access Devices), PBXs and line cards.
