MT8941B Datasheet (Zarlink Semiconductor) - Advanced T1/CEPT Digital Trunk PLL

MT8941B, Advanced T1/CEPT Digital Trunk PLL

The MT8941B is a dual digital phase-locked loop providing the timing and synchronization signals for the T1 or CEPT transmission links and the ST-BUS.

The first PLL 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
