Abstract
A communication unit () is described that includes a plurality of cascaded devices that includes at least one master device and at least one slave device configured in a master-slave arrangement. The at least one master device comprises a modulator circuit () configured to: receive a system clock signal and a frame start signal; modulate the system clock signal with the frame start signal to produce a modulated master-slave clock signal (); and transmit the modulated master-slave clock signal () to the at least one slave device. The at least one slave device comprises a demodulator circuit () configured to: receive and demodulate the modulated master-slave clock signal (); and re-create therefrom the system clock signal () and the frame start signal ().
