MT9041数据手册集成电路（IC）的电信规格书PDF

描述 Description

The MT9041B T1/E1 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 MT9041B generates ST-BUS clock and framing signals that are phase locked to either a 2.048 MHz, 1.544 MHz, or 8 kHz input reference. The MT9041B is compliant with AT&T TR62411 and Bellcore GR-1244-CORE Stratum 4 Enhanced, Stratum 4, and ETSI ETS 300 011. It will meet the jitter tolerance, jitter transfer, intrinsic jitter, frequency accuracy, capture range and phase change slope requirements for these specifications.
