General Description
MT9040 General Description
The MT9040 T1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization signals for T1 and E1 primary rate transmission links.
The MT9040 generates ST-BUS clock and framing signals that are phase locked to either a 19.44 MHz, 2.048MHz, 1.544MHz, or 8kHz input reference.
The MT9040 is compliant with AT&T TR62411 and Bellcore GR-1244-CORE, Stratum 4; and ETSI ETS 300 011. It will meet the jitter/wander tolerance, jitter transfer, intrinsic jitter, frequency accuracy and capture range for these specifications.
