A timer circuit for a video camera capable of generating a video signal having time code information associated to its frames comprises:
an input port for receiving an external serial digital time code signal (LTC external),
an interface circuit (10) for extracting from said time code signal (LTC) a phase signal (LTC-bit-phase-ext) synchronized to the bit frequency of said serial digital time code signal (LTC);
a phase-locked loop (9, 33, 35) controlled by said phase signal to deliver a pixel clock signal in synchronism with the phase signal.
