Product Summary

The mt8941bp is an Advanced T1/CEPT Digital Trunk PLL. It provides the timing and synchronization signals for the T1 or CEPT transmission links and the ST-BUS. The first PLL of the mt8941bp provides the T1 clock (1.544 MHz) synchronized to the input frame pulse at 8 kHz. The timing signals for the CEPT transmission link and the ST-BUS are provided by the second PLL locked to an internal or an external 8 kHz frame pulse signal. The applications of the mt8941bp include: Synchronization and timing control for T1 and CEPT digital trunk transmission links, ST- BUS clock and frame pulse source.
