Abstract
The communication system having a transmitter and a receiver, wherein the transmitter and the receiver are coupled by a clock channel and a data channel, wherein the clock channel is shorter than the data channel and wherein the receiver comprises a delay circuit for extracting a jitter signal from a clock channel signal, delaying the extracted jitter signal, and generating a receiver clock signal for the receiver by means of the delayed jitter signal.
Claims13
A communication system comprising:
- a transmitter;
- a receiver, and
- a clock channel and a data channel coupling the transmitter and the receiver, wherein the clock channel is shorter than the data channel, and
- wherein the receiver comprises a delay circuit for extracting a jitter signal from a clock channel signal, delaying the extracted jitter signal, and generating a receiver clock signal for the receiver by means of the delayed jitter signal.
A receiver for a source-synchronous communication system, wherein the receiver comprises a delay circuit and wherein the delay circuit is provided for
- extracting a jitter signal from a received clock channel signal,
- delaying the extracted jitter signal,
- generating a receiver clock signal for the receiver by means of the delayed jitter signal.
A method for synchronizing a clock channel signal and a data channel signal of a source-synchronous communication channel, wherein the clock channel and the data channel comprise a propagation delay time difference, the method comprising the steps of:
- receiving the clock channel signal and the data channel signal,
- extracting a jitter signal from the received clock channel signal,
- delaying the extracted jitter signal,
- generating a receiver clock signal by means of the delayed jitter signal.
