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.

The MT8940 is fabricated in MITEL鈥檚 ISO-CMOS

technology.

Applications

鈥?/div>

Synchronization and timing control for T1

and CEPT digital trunk transmission links
