General Description

The MT8940 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 the ST-BUS are provided by the second PLL locked to an internal or an external 8 kHz frame pulse signal.

Key Features
