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. It
meets 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.
