Abstract: 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.

Abstract: A circuit includes an amplifier including a differential input stage including a first input terminal and a second input terminal. The circuit further includes a differential input line coupled to the first input terminal and the second input terminal, and shielding at least partially encompassing the differential input line. The shielding is connected to a node of the differential input stage of the amplifier.

Abstract: A first systolic array receives an input set of time division multiplexed matrices from a plurality of channel matrices. In a first mode, the first systolic array performs triangularization on the input matrices, producing a first set of matrices, and in a second mode performs back-substitution on the first set, producing a second set of matrices. In a first mode, a second systolic array performs left multiplication on the second set of matrices with the input set of matrices, producing a third set of matrices. In a second mode, the second systolic array performs cross diagonal transposition on the third set of matrices, producing a fourth set of matrices, and performs right multiplication on the second set of matrices with the fourth set of matrices. The first systolic array switches from the first mode to the second mode after the triangularization, and the second systolic array switches from the first mode to the second mode after the left multiplication.
