Description

The MT9041 is a digital phase-locked loop (PLL) designed to provide timing and synchronization signals for T1 and E1 primary rate transmission links that are compatible with ST-BUS/GCI frame alignment timing requirements. The PLL outputs can be synchronized to either a 2.048 MHz, 1.544 MHz, or 8 kHz reference. The T1 and E1 outputs are fully compliant with AT & T TR62411 (ACCUNET? T1.5) and ETSI ETS 300 011 intrinsic jitter and jitter transfer specifications, respectively, when synchronized to primary reference input clock rates of either 1.544 MHz or 2.048 MHz.

Features

? Provides T1 and E1 clocks, and ST-BUS/GCI framing signals locked to an input reference of either 8 kHz (frame pulse), 1.544 MHz (T1), or 2.048 MHz (E1)

? Meets AT & T TR62411 and ETSI ETS 300 011 specifications for a 1.544 MHz (T1), or 2.048 MHz (E1) input reference

? Typical unfiltered intrinsic output jitter is 0.013 UI peak-to-peak

? Jitter attenuation of 15 dB @ 10 Hz, 34 dB @ 100 Hz and 50 dB @ 5 to 40 kHz

? Low power CMOS technology

Applications

? Synchronization and timing control for T1 and E1 digital transmission links

? ST-BUS clock and frame pulse sources

? Primary Trunk Rate Converters
