meets phase slope and MTIE requirements
Operates in either Normal, Holdover and
Freerun modes
Applications
Synchronization and timing control for
multitrunk T1 and E1 systems
ST-BUS clock and frame pulse sources
Primary Trunk Rate Converters
Description
The MT9042C Multitrunk System Synchronizer
contains a digital phase-locked loop (DPLL), which
provides timing and synchronization signals for
multitrunk T1 and E1 primary rate transmission links.
The MT9042C generates ST-BUS clock and framing
signals that are phase locked to either a 2.048MHz,
1.544MHz, or 8kHz input reference.
The MT9042C is compliant with AT&T TR62411
Stratum 3, 4 and 4 Enhanced, and ETSI ETS 300
011. It will meet the jitter tolerance, jitter transfer,
intrinsic
jitter,
frequency
accuracy, capture range, phase slope and MTIE
requirements for these specifications.
