Abstract
Disclosed is a receiver, which includes a CDR (clock and data recovery) module that recovers a clock and data from a PAM (pulse amplitude modulation)-3 signal received through a communication channel based on a first coefficient for equalizing and recovering the data and a second coefficient for equalizing and recovering the clock, and an adaptation module that controls the first coefficient and the second coefficient.
Claims9
A receiver comprising:
- a CDR (clock and data recovery) module configured to recover a clock and data from a PAM (pulse amplitude modulation)-3 signal received through a communication channel based on a first coefficient for equalizing and recovering the data and a second coefficient for equalizing and recovering the clock;
- and
- an adaptation module configured to control the first coefficient and the second coefficient.
A method of operating a receiver for recovering a clock and data, in a process of sampling a PAM-3 signal received through a communication channel, the method comprising:
- matching sizes of a pre-cursor and a post-cursor;
- obtaining a size of a main cursor;
- obtaining a first coefficient for data recovery;
- increasing and decreasing a second coefficient by dividing conditions into comparing the size of the obtained main cursor with a size of a next order main cursor, and comparing the first coefficient with a next order first coefficient;
- and
- returning to the obtaining the size of the main cursor, to iterate the operations in order.
