Plesiochronous clock generation for parallel wireline transceivers |
摘要 |
A method for plesiochronous clock generation for parallel wireline transceivers, includes: inputting, into at least one decoder, at least one digital frequency mismatch number; decoding, with the at least one decoder, the at least one digital frequency mismatch number to obtain at least one digital frequency divider number that represents a transmit frequency associated with at least one signal; inputting the at least one digital frequency divider number into at least one fractional-N phase lock loop; and utilizing, by the at least one fractional-N phase lock loop, the at least one digital frequency divider number and an analog reference signal produced by a reference oscillator to produce a resultant signal at the transmit frequency; wherein the at least one decoder and the at least one fractional-N phase lock loop are contained on a single integrated circuit. |

1. A method, comprising:
inputting at least one digital frequency mismatch number; decoding, with the at least one decoder, the at least one digital frequency mismatch number to obtain at least one digital frequency divider number that represents a transmit frequency associated with at least one signal; inputting the at least one digital frequency divider number into at least one fractional-N phase lock loop; and utilizing, by the at least one fractional-N phase lock loop, the at least one digital frequency divider number and an analog reference signal produced by a reference oscillator to produce a resultant signal at the transmit frequency; wherein the at least one fractional-N phase lock loop is integrated into a transceiver of an integrated circuit, and wherein the integrated circuit includes the at least one decoder. |
