* Exceeding these values may cause permanent damage. Functional operation under these conditions is not implied.DescriptionThe MT9041AP is one member of the MT9041 family which is designed as the T1/E1 system synchronizer device that can be used in (1)Synchronization and timing control for multitrunk T1 and E1 systems; (2)ST-BUS clock and frame pulse sources applications. This device generates ST-BUS clock and framing signals, and will meet the jitter tolerance, jitter transfer, intrinsic jitter, frequency accuracy, capture range and phase change slope requirements for these specifications.
Features of the MT9041AP are:(1)Supports AT&T TR62411 and Bellcore GR-1244-CORE Stratum 4 Enhanced and Stratum 4 timing for DS1 Interfaces; (2)Supports ETSI ETS 300 011, TBR 4, TBR 12 and TBR 13 timing for E1 Interfaces; (3)Selectable 1.544MHz, 2.048MHz or 8kHz input reference signals; (4)Provides C1.5, C2, C3, C4, C8 and C16 output clock signals; (5)Provides 3 different styles of 8 KHz framing pulses; (6)Attenuates wander from 1.9 Hz.
The absolute maximum ratings of the MT9041AP can be summarized as:(1)Supply voltage: -0.3 to 7.0 V;(2)Voltage on any pin: -0.3 to VDD+0.3 V;(3)Current on any pin: 20 mA;(4)Storage temperature: -55 to 125 °C;(5)PLCC package power dissipation: 900 mW.
