Abstract
A clock and data regenerator for different data rates including a control loop which is controlled by a phase discriminator (PD) and two frequency discriminators. The first frequency discriminator enlarges the catchment range of the control loop. The second frequency discriminator determines the ratio of the bit rates of the clock signal and of the data signal. The second frequency discriminator sets the loop frequency divider appropriately, and supplies a control voltage for setting the oscillator until the first frequency discriminator can carry out this function.
