Abstract
A link establishment apparatus is configured to connect to another apparatus via an interface of JESD204B and perform a link establishment procedure for establishing a link with such another apparatus, the link establishment apparatus being further configured to receive a first parameter of JESD204B from the other apparatus in the link establishment procedure, and, in a case in which a second parameter of JESD204B configured in the link establishment apparatus does not match the received first parameter, change the second parameter to match the first parameter.
Claims5
A link establishment apparatus configured to connect to another apparatus via an interface of JESD204B and perform a link establishment procedure for establishing a link with the another apparatus, the link establishment apparatus comprising:
- one or more memories storing instructions;
- and
- one or more processors configured to execute the instructions to
- receive a first parameter of JESD204B from the another apparatus in the link establishment procedure;
- and
- in a case in which a second parameter of JESD204B configured in the link establishment apparatus does not match the received first parameter, change the second parameter to match the first parameter, wherein
- in an Initial Lane Alignment Sequence (ILAS) state of JESD204B, the one or more processors is configured to receive a multi-frame from the another apparatus, and extract the first parameter from the multi-frame, and
- the one or more processors is configured to compare the extracted first parameter and the second parameter, and determine whether or not the second parameter matches the first parameter,
- the link establishment apparatus further comprises a clock driver configured to transmit a SYSREF signal in JESD204B to the link establishment apparatus and the another apparatus,
- the one or more processors is configured to compare a third parameter calculated from the extracted first parameter and a fourth parameter configured in the clock driver, and
- in a case in which the third parameter does not match the fourth parameter, the one or more processors is configured to change the fourth parameter configured in the clock driver.
A link establishment apparatus configured to connect to another apparatus via an interface of JESD204B and perform a link establishment procedure for establishing a link with the another apparatus, the link establishment apparatus comprising:
- one or more memories storing instructions;
- and
- one or more processors configured to execute the instructions to
- receive a first parameter of JESD204B from the another apparatus in the link establishment procedure;
- and
- in a case in which a second parameter of JESD204B configured in the link establishment apparatus does not match the received first parameter, change the second parameter to match the first parameter, wherein
- the first parameter includes a first data rate,
- the second parameter includes a second data rate, and
- in a case in which the first data rate and the second data rate do not match, the one or more processors is configured to change the second data rate to match the first data rate.
A method performed in a link establishment apparatus configured to connect to another apparatus via an interface of JESD204B and perform a link establishment procedure for establishing a link with the another apparatus, the method comprising:
- receiving a first parameter of JESD204B from the another apparatus in the link establishment procedure;
- and
- in a case in which a second parameter of JESD204B configured in the link establishment apparatus does not match the received first parameter, changing the second parameter to match the first parameter, wherein the method further comprises:
- in an Initial Lane Alignment Sequence (ILAS) state of JESD204B, receiving a multi-frame from the another apparatus, and extracting the first parameter from the multi-frame,
- comparing the extracted first parameter and the second parameter, and determining whether or not the second parameter matches the first parameter;
- the link establishment apparatus comprises a clock driver configured to transmit a SYSREF signal in JESD204B to the link establishment apparatus and the another apparatus, and
- the method further comprises:
- comparing a third parameter calculated from the extracted first parameter and a fourth parameter configured in the clock driver, and
- n a case in which the third parameter does not match the fourth parameter, changing the fourth parameter configured in the clock driver.
