Communication unit, integrated circuit and method for clock distribution and synchronization

An integrated circuit for a device in a master-slave arrangement, wherein the integrated circuit is characterized by a demodulator circuit configured to:

• receive a modulated embedded master-slave clock signal that comprises a system clock signal with an embedded frame start signal;
• demodulate the modulated embedded master-slave clock signal;
• and
• re-create therefrom the system clock signal and the frame start signal.

A method for clock distribution and synchronization in a communication unit having at least one master device and at least one slave device configured in a master-slave arrangement and configured to process at least one of:

• transmit signals, and receive signals, wherein the method comprises, at a master device:
• receiving a modulated embedded master-slave clock signal that comprises a system clock signal with an embedded frame start signal;
• demodulating the modulated embedded master-slave clock signal;
• and
• re-creating therefrom the system clock signal and the frame start signal.
