Abstract
A radar device comprises a data communication input interface configured to receive a data clock signal for a data bus and an analog to digital converter configured to sample a signal at time instants given by a sampling clock signal. In an implementation, a sampling clock generation circuit is configured to generate the sampling clock signal based on the data clock signal.
Claims20
A radar device, comprising:
- a data communication input interface configured to:
- receive a data clock signal for a data bus;
- an analog to digital converter configured to:
- sample a signal at time instants given by a synchronized sampling clock signal;
- and
- a sampling clock generation circuit configured to:
- perform synchronization of a sampling clock signal to a predetermined cycle of the data clock signal, and
- generate the synchronized sampling clock signal based on performing the synchronization.
